Application: telepathy-kde-contactlist (0.1) KDE Platform Version: 4.7.00 (4.7.0) Qt Version: 4.7.4 Operating System: Linux 3.0.0-4-desktop x86_64 Distribution: "openSUSE 12.1 Milestone 2 (x86_64)" -- Information about the crash: - What I was doing when the application crashed: in the buddy list I simply try to add a new contact (+ button). The following dialog is showing an empty account combo box and a field for the screen name. Since I can't do anything about an empty combo box I can only add a screen name and try to head on. That's when the crash happens. -- Backtrace: Application: Telepathy KDE Contact List (telepathy-kde-contactlist), signal: Segmentation fault [Current thread is 1 (Thread 0x7f9c75583760 (LWP 8419))] Thread 3 (Thread 0x7f9c6630f700 (LWP 8425)): #0 0x00007f9c7010a0eb in pthread_cond_timedwait@@GLIBC_2.3.2 () from /lib64/libpthread.so.0 #1 0x00007f9c7358100e in QWaitCondition::wait(QMutex*, unsigned long) () from /usr/lib64/libQtCore.so.4 #2 0x00007f9c73575a7f in ??

Is your account (any) connected?
Good spot, main-widget.cpp:712 needs a check that the returned account is valid. Checking account->connection() should be safe enough, and catch issues with the account disconnecting too. As for the empty list, I would also guess that one of the accounts is offline. We also hide any accounts which do not support adding of contacts (IRC, for example). I'm confirming the crash is valid, the "empty list" needs more info. - what accounts do you have. - are you sure they were connected. This should probably be a separate bug report to the crash, as they're not related.

I tried with both bonjour and SIP account, both were connected (I don't know about the situation when I reported, at least it definitely happens when connected too). My google IM account does not connect due to a network error, which I can't track down (have not found any logfiles or anything, so no bug report about that unfortunately).
