Crash upon opening a conversation

[karllindmark]

Hello world!

Seeing that Skype is crashing when I'm running it with skype-ng and opening a conversation window, I might as see if I can help you guys this error. :-)

What kind of debug should I pull, and how do I get it?

Running Arch Linux (i686) and pekwm

I can confirm this bug running Gentoo Linux on x86!

When I run skype with gdb I get the following:

moschlar@mopad ~/src/skypetab-ng $  echo $LD_LIBRARY_PATH
:/opt/skype
moschlar@mopad ~/src/skypetab-ng $ echo $LD_PRELOAD
/home/moschlar/src/skypetab-ng/libskypetab-ng.so
moschlar@mopad ~/src/skypetab-ng $ cd /opt/skype/
moschlar@mopad /opt/skype $ gdb ./skype

Thank you for this report. Please, check that the issue still present after this commit

[moschlar]

Hey kekekeks, I've tested and now skype doesn't crash anymore (running with gdb) but the chat window doesn't open!
When I click on a contact or on the chat bubble, just nothing happens!

[kekekeks]

Which window manager and Qt version are you using?

[moschlar]

This is Qt 4.7.2 under Gnome 2.32.1 with Metacity 2.30.3!

[kekekeks]

Try to update, it seems that after a fix proposed by restorer it works on Gentoo.

[moschlar]

Yep, thanks, it works now!
Great job!
