Licq SVN Version Crashes (segfault) on message sent (qt4-gui)

[syn]

Hi i updated my SVN version of LICQ yesterday, and i compiled the first time the qt4-gui. Unfortunately on every message send, independant of the Protocol used it crashes.

See gdb below.

(i X ed out the recipient)

Anyone can confirm, and or fix? :-)

Thanks, Syn

It looks like the stack trace isn't complete, could you please attach a complete backtrace, preferably of all threads. (When licq crashes, you should get ~/.licq/licq.backtrace.gdb which contains just that.)

[syn]

Stacktrace complete

[syn]

Stacktrace added, though licq didn't generated it by itselv. Another strange thing is the 500.000 lines generated in the backtrace, that's why i tar'ed it. Good luck! (i deleted the unimportant packet information for privacy reasons)

[flynd]

Patch for init order of mmuserview that might help

[flynd]

I wasn't able to reproduce this, but after looking at the stack trace I made a guess of what might cause the prablem. Could you please try the patch I've just attached and let me know if it solves the problem.

[syn]

Unfortunately the patch did not solve the problem. But thanks for looking into this.

new Backtrace attached.

[flynd]

I still don't know why it's happening. But the change in r6707 should make sure the problem doesn't appear when sending a message. Please update to latest svn and try again.

However, I suspect that this crash can still appear if toggling the multiple recipients function in the message dialog. Could you please test this for me as well.

Also, I would like to know which Qt version you are using.
