Version: (using KDE 4.2.2) OS: Linux Installed from: Ubuntu Packages Many KDE applications (Plasma, Dolphin, Konqueror, Ksystemlog, Gwenview and others... ) occasionally crash on my computer with signal 11 (SIGSEGV). (What the heck does it mean?) Here's one crash which seems (with a little chance) reproducible: I start the computer, I open a photo directory with Gwenview and rotate some photos. After 20 rotations, Gwenview suggests me to record the modifications. Which I do. There, often, Gwenview crashes with signal 11 (SIGSEGV). I currently use Kubuntu Jaunty. I had some signal 11 (SIGSEGV) on this computer with previous versions of Kubuntu (Hardy) and the current one, Jaunty was a fresh new installation. I also checked my Ram memory and it's fine. Here are the details I could get: Application : Gwenview (gwenview), signal SIGSEGV [Current thread is 0 (LWP 3100)] Thread 2 (Thread 0xb442fb90 (LWP 3101)): #0 0xb7f85430 in __kernel_vsyscall () #1 0xb5f150e5 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/tls/i686/cmov/libpthread.so.0 #2 0xb65d92ed in pthread_cond_wait () from /lib/tls/i686/cmov/libc.so.6 #3 0xb79ee9b2 in QWaitCondition::wait (this=0x8ba1098, mutex=0x8ba1094, time=4294967295) at thread/qwaitcondition_unix.cpp:87 #4 0xb7ed566f in ??

@Grasyop: if any other application is crashing, report every crash individually. Hopefully , a lot of crashes are already addressed on KDE4.3 This crash is a duplicate of bug 189992. Thanks *** This bug has been marked as a duplicate of bug 189992 ***
All right, thank you very much.
