Application: digikam (2.5.0) KDE Platform Version: 4.8.3 (4.8.3) Qt Version: 4.8.1 Operating System: Linux 3.2.0-25-generic x86_64 Distribution: Ubuntu 12.04 LTS -- Information about the crash: - What I was doing when the application crashed: Performing a scan of my image collection using the "Scan collection for faces" button. It has failed repeatedly during this endevor. The first time was after about 30%, second after about 61%, then about every 4% after. I have tried with and without using all CPU cores for this task with no change in behavior. This is a large collection of photos, about 18,000 totaling around 34GB. The crash can be reproduced every time. -- Backtrace: Application: digiKam (digikam), signal: Aborted Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". syscall () at ../sysdeps/unix/sysv/linux/x86_64/syscall.S:39 [Current thread is 1 (Thread 0x7f60a3f29a00 (LWP 26297))] Thread 24 (Thread 0x7f607f915700 (LWP 26301)): #0 pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:162 #1 0x00007f609e1a74db in wait (time=18446744073709551615, this=0x2bfea20) at thread/qwaitcondition_unix.cpp:86 #2 QWaitCondition::wait (this=<optimized out>, mutex=0x2bfe918, time=18446744073709551615) at thread/qwaitcondition_unix.cpp:158 #3 0x00000000005ca1d0 in ??

I've seen this bt before, but there's nothing helping me to find a bug unless I can reproduce this myself one day.
Official digiKam 2.6.0 release is out since few days now : http://www.digikam.org/drupal/node/656 Please, check if this entry still valid, or update report accordingly. Thanks in advance. Gilles Caulier
digiKam 4.0.0 is out : http://www.digikam.org/node/713 Please check if this entry still valid with this new version. Thanks in advance Gilles Caulier
With next digiKam 4.1.0, i fixed libkface to handle all C++ exception (and not only OpenCV exception). So, at least, digiKam must crash lesser now. If you want to review this entry again, use current implementation from git/master, or wait next 4.1.0 release... Thanks to update your feedback Gilles Caulier

With next digiKam 4.1.0, a lots of improvements/fixes have be done around face management. Please give us a fresh feedback. Note i recommend to delete face recognition database to prevent dysfunction due to possible wrong data store in this container.

We need a fresh feedback of this file using last digiKam 4.2.0 Gilles Caulier
New digiKam 4.11.0 is available : https://www.digikam.org/node/740 Can you reproduce the problem with this release ? Gilles caulier
digiKam 4.12.0 is out : https://www.digikam.org/node/741 We need a fresh feedback using this release please... Thanks in advance.
With next 5.1.0 release, a lots of investigations have be done around OpenCV face module integration with digiKam Face Engine. See bug #365202 history for details. I close this file now. Don't hesistate to re-open if necessary. Gilles Caulier
