Unable to launch muCommander on a 10.4.10 PowerBook

[TvE]

When trying to launch muCommander (both 0.8.0 & 0.8.1) on my 867 MHz PowerBook running a fully updated 10.4.10 (even reinstalled "JavaForMacOSX10.4Release5.pkg") it hangs when it tries to "initialize window". It alerts an error:

Code: Select all

Cannot launch application

Uncaught exception in main method:
java.lang.illegalArgumentException: Width 0) and Height (0) must be non-zero

And a log "JavaNativeCrash_pid770" contains the information:

The most interesting is probably in console.log:

I then have to force quit muCommander

muCommander runs perfectly on my mainmachine (a 24" iMac) - but my testmachine (the PPC PowerBook) also need it…




PS.: The java installations I have done on the machine are:
2006.01.26 SWU: Java 1.3.1 and 1.4.2 Release 2 2.0
2007.03.18 JavaForMacOSX10.4Release5.pkg
2007.10.07 JavaForMacOSX10.4Release5.pkg (reinstalled due to a muCommander error)



PPS.: Perhaps relevant - I am capable of running other java apps, EG.: Zend Studio 5.1

[TvE]

My 10.4.10 Server (a dual 450 MHz PPC G4) behaves in the same way - at least it displays the same dialog (did not go to the logs…)


Hmm(!!!)

[TvE]

Hmm - now I have also tried the installation om a G5 iMac and am getting the same error alerted to me.

I even decompressed the nightly build via the shell just in case the old StuffIt problems might be the cause

Hey there,

I think I might finally have figured out what the problem was. I've just commited a potential fix to CVS, can you wait until tomorrow, get the nightly build and try again?

Cheers,
Nicolas

Naturally(!) - looking forward to DL'ing it 2morrow

Hi TvE,
The nightly build has just been rebuilt, you can download it whenever you like. The fix may or may not work.

Additionally, I have a few questions for you which will help pinpoint the exact cause of the problem, both in 0.8 (final) and 0.8.1 (nightly build) :

1) I have generated a 0.8 build with full stack trace symbols (no obfuscation) :
http://www.mucommander.com/download/muc ... _unobf.jar
Could you please download this build and copy/paste the stack trace you got in your console.log file here ?

2) Same thing for the nightly build (0.8.1) if the fix didn't work :
http://www.mucommander.com/download/nig ... _unobf.jar

3) Are you using Java 1.4 on all the machines that exhibit this problem ?

Thanks a lot for your help!
Maxence

Thanx again for the prompt response! Unfortunately I am still unable to launch succesfully (on the G5). But I do not get any alerts, just the output shown below.

The Java version is what Apple has provided me with via Software Update - I have not made any "unauthorized" installations:

Thanks a lot for this detailed report! That should be all we need to fix the bug.
I'll let you know when a potential fix has been issued, hopefully today.

[maxence]

Actually now that I have looked into it, I have another question for you :)

Could you please open the preferences file on one of the machines where muCommander can't launch (~/Library/Preferences/muCommander/preferences.xml) and check the value of the following element :

Code: Select all

<prefs>
  <file_table>
    <icon_scale>


It contains a numeric value that is normally greater or equal to 1.0.
I suspect this value to be 0.0 and cause the problem you're experiencing. If that is the case, you can change it to 1.0 to fix the startup issue until it gets fixed in muCommander.

Thanks!
Maxence

I am testing it on my G4:
You're correct - the value is 0.0, but changing it makes no difference - I still get the same error


BUT if I also change the other places where the icon_scale is (pre-)set to 0.0 THEN I can get muCommander to launch(!)

Code: Select all

    <toolbar>
        <icon_scale>1.0</icon_scale>
        <visible>true</visible>
    </toolbar>
    <command_bar>
        <icon_scale>1.0</icon_scale>


Now if I could also get it to run on my company XP machine http://www.mucommander.com/forums/viewtopic.php?t=571 then I can use the same nice app on both my platforms - Currently I am using Total Commander (the first OFM I began to use - then all other "normal" file managers suddenly looks very crappy)

[TvE]

And it's also working on my G5 after changing the three values for icon_scale from 0.0 to 1.0

[maxence]

OK, thanks for the follow up! I'm glad you can launch muCommander again under OS X. Tonight's nightly build will contain a patch for the startup problem, should other people have bogus values in their configuration. Now, what I need to find out is how in the world those values got set to 0.0...

I'll reply to the XP problem in the other thread. Man, you're not being very lucky with muCommander and I'm thankful you're not giving up entirely :)
