Application: digikam (4.4.0) KDE Platform Version: 4.13.3 Qt Version: 4.8.6 Operating System: Linux 3.13.0-35-generic x86_64 Distribution: Ubuntu 14.04.1 LTS -- Information about the crash: - What I was doing when the application crashed: I was clicking through individual images in the image bar on top, with large image preview, and I had previously started a face recognition run. The crash occurred after I have just switched to a new image. Note the crash handler is launched from Thread #7, trying to acquire an Exif preview image. -- GIT VERSIONS: $ ./gits rev-parse HEAD On: extra/kipi-plugins: e10b532dc526cb4d9d85a89b2eb27cad73ecaf5f On: extra/libkgeomap: 9236be037d43c5b3683b6e196691d893054376a7 On: extra/libksane: b49db73ff168c3f4099a0375976a0a9fecd2b190 On: .: a0f5c8c0dbac4045bff6c1828e68282acff362c6 On: extra/libkdcraw: 45dd49cef396fd63134efce15cc73b823a6b26fd On: extra/libmediawiki: c0c916e436a2f405881fba3a7375af114c2b8999 On: core: dab4a123593bddadf00862260bb92f159118157a On: extra/libkvkontakte: fdc54a6cb28a02d9b826defc584d69b971225a1b On: extra/libkipi: 49458c4c1abc409a75690db9d6484f89069ef7b0 On: doc/kipi-plugins: 7c09f1949236894419efd62ae6ca8ad27f196253 On: extra/libkface: dd06888900c6ed226a9d277366716d386f51e1cd On: doc/digikam: 691abb3aa5dac59e3897936bb45c5924c3dc5990 On: extra/libkexiv2: de62cac2cbcf1c02db435dd8058e8fbe3245cd1c -- Backtrace: Application: digiKam (digikam), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:185 [Current thread is 1 (Thread 0x7f8ef53b4ac0 (LWP 1534))] Thread 29 (Thread 0x7f8eccd04700 (LWP 1535)): #0 0x00007f8eedf6ac6d in poll () at ../sysdeps/unix/syscall-template.S:81 #1 0x00007f8ed297f248 in ??

I haven't found an image path printed in .xsession-errors nor on the console. If there is a way to run digikam with extended debugging information, please point me to the instructions. While trying to reproduce, I got this in the console: KCrash: Application 'digikam' crashing...

It crash in Exiv2 shared library. Please report this problem to Exiv2 bugzilla. Don't forget to found a relevant image causing this crash. Gilles Caulier
Gilles, is there an exiv2 test program, either in libkexiv2, or in digikam, that should also crash on the same "image" (aka AVI movie file)? I can't get exiv2 to crash on the same file, but it constantly prints an exception on the command line, so I am wondering if digikam has an exception handler in the right spot and/or is feeding libkexiv2 proper data given the many 0s in Comment #3.
>is there an exiv2 test program, ==> exiv2 CLI tool > I can't get exiv2 to crash on the same file, but it constantly prints an exception on the command line, so I am wondering if digikam has an exception handler ==> yes, it is, in libkexiv2 interface. The crash appears with preview extraction. Code is here : https://projects.kde.org/projects/kde/kdegraphics/libs/libkexiv2/repository/revisions/master/entry/libkexiv2/kexiv2previews.cpp > + -DDIGIKAMSC_USE_PRIVATE_KDEGRAPHICS=OFF \ ==> no. Use last libkexiv2 code and uninstall system wide libkexiv2. Gilles Caulier
I switched ...USE_PRIVATE_KDEGRAPHICS back to on, and cmake complained that my exiv2 is too old. Would that be the cause of the trouble? If so, a version check of (k)exiv2 on digikam start-up might be in order. I will try to upgrade exiv2 later and then rebuild digikam to see if this fixes this problem. Thanks for the prompt replies.
With incoming 6.0.0 release the video metadata parser will be delegate to ffmpeg instead Exiv2. This problem will not be reproducible. Gilles Caulier
