Application: ktorrent (4.0.5) KDE Platform Version: 4.6.2 (4.6.2) Qt Version: 4.7.2 Operating System: Linux 2.6.38-11-generic x86_64 Distribution: Ubuntu 11.04 -- Information about the crash: I was just browsing the web in Google Chrome (not watching videos) and downloading a few patches for games using Ktorrent, I'm running Kubuntu 11.04 AMD64 on a Compaq Presario CQ60-420US laptop, and Ktorrent just up and crashed (no warning) and when I restarted it, it ran just fine. The crash does not seem to be reproducible. -- Backtrace: Application: KTorrent (ktorrent), signal: Segmentation fault [Current thread is 1 (Thread 0x7f6da6239780 (LWP 1580))] Thread 6 (Thread 0x7f6d91dc1700 (LWP 1713)): #0 0x00007f6d9efbec32 in __pthread_getspecific (key=<value optimized out>) at pthread_getspecific.c:62 #1 0x00007f6da3e68241 in get_thread_data () at thread/qthread_unix.cpp:161 #2 QThreadData::current () at thread/qthread_unix.cpp:199 #3 0x00007f6da3f79e99 in postEventSourcePrepare (s=0x18877b0, timeout=0x7f6d91dc0c4c) at kernel/qeventdispatcher_glib.cpp:254 #4 0x00007f6d9e0aa0a2 in g_main_context_prepare () from /lib/x86_64-linux-gnu/libglib-2.0.so.0 #5 0x00007f6d9e0aaf9d in ??
