Bug 125547

Bug 123082 was closed because i couldn't reproduce it and no backtrace was provided. I still cannot reproduce it. Can you give us a valid backtrace?

I compiled from source with full debug info.
Here's an even simpler way to reproduce the crash.
1- compress a music with bzip2
2- ark blah.bz2
3- play the music
4- launch ark blah.bz2 again

Most of the time it says the backtrace is useless ( too corrupt ) but I managed to get one:
Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".

Here is also the debug output from the command line

arthurb@coin:~$ ark blah.mp3.bz2
Already running
ark (kdeutils): ArkPart::ArkPart
ark (kdeutils): ArkWidget::createFileListView
KCrash: Application 'ark' crashing...
ERROR: Communication problem with ark, it probably crashed.

when playing I also have the following warning... it's not what makes the app crash but maybe it is related:

kparts: WARNING: StatusBarExtension::removeStatusBarItem. Widget not found : [KPushButton pointer (0x8103d08) to widget CancelButton, geometry=100x30+0+0]


regards

I still cannot reproduce it :/
Before running again ark, did you close the previous ark window?
