Application that crashed: digikam Version of the application: 1.2.0 KDE Version: 4.3.5 (KDE 4.3.5) "release 0" Qt Version: 4.5.3 Operating System: Linux 2.6.31.12-0.2-default i686 Distribution: "openSUSE 11.2 (i586)" What I was doing when the application crashed: Using: - OpenSuSE 11.2, x86 32-bit - KDE 4.3.5 (stock version provided with this version of openSuSE, localisation dutch-NL) - digikam 1.2.0 (from openSuSE build service: download.opensuse.org/repositories/home:/enzokiel/openSUSE_11.2_Update) After making some minor changes to 2 or 3 photographs (rotating clockwise and anti-clockwise) and saving the quasi-changed image, digikam crashes after the user answered the question wether the existing image should be overwritten. (No save as... used, just clicking "Next image" every time and affirming that the changed image should be saved). Just doing the minor changes without saving doesn' t crash digikam. What is going on? Happy bug hunting. -- Backtrace: Application: digiKam (digikam), signal: Segmentation fault [Current thread is 1 (Thread 0xb2c29700 (LWP 8935))] Thread 19 (Thread 0xb15a1b70 (LWP 8936)): #0 0xffffe430 in __kernel_vsyscall () #1 0xb4a8cd95 in pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/i386/i486/pthread_cond_wait.S:122 #2 0xb4b7e27c in pthread_cond_wait () from /lib/libc.so.6 #3 0xb4d8a750 in wait (time=<value optimized out>, this=<value optimized out>) at thread/qwaitcondition_unix.cpp:87 #4 QWaitCondition::wait (time=<value optimized out>, this=<value optimized out>) at thread/qwaitcondition_unix.cpp:159 #5 0x083549ba in ??

QString crash in kio ??? Gilles Caulier
Gilles, does it help you if I post the results of a Digikam crash with libkio-debuginfo installed?
yes probably. I suspect a crash relevant of KDirWatch api... Look there : https://bugs.kde.org/show_bug.cgi?id=222974 Gilles Caulier
Hello Giles Installed libkde4-debuginfo, but the lines about libkio.so still contain question marks. BTW: The version number of the libkde4-debuginfo package is still 4.3.1 (original KDE version in openSuSE 11.2) instead of 4.3.5 (present KDE version and libkde4 version in openSuSE 11.2), so maybe it just doesn't work because they forgot to update it when they updated the rest of KDE....

It sound like the famous KDirWatch crash from KDE 4.3.x Can you update KDE to a more recent version as 4.4 for example, By the same time, updating digiKam to 1.4.0 will be great Gilles Caulier
Thanks for the tip. I will test this, but changing KDE is not something I want to do on a "production" machine. So lots of work ahead, stay tuned...
Upgraded KDE to version 4.4.4 from the OBS, using Digikam version 1.2.0. No more crashes, so it seems to bee a KDE problem after all. Thanks for providing the solution, Gilles!
Since digiKam 5.0.0, KDirWatch was been replaced by QFileSytemWatcher. It will not reproducible. Gilles Caulier
