Description Micha 2012-09-20 16:26:44 UTC
Digikam's face detection is not very reliable, quite often the squares it defines are not around the actual location of a face or faces are not detected at all (especially if they aren't looking directly at the camera).  Therefore, after automatic detection runs, I have to manually go over the albums and add tags.  Every time I do this, after adding tags to some images Digikam crashes.  This does not happen during adding the tags themselves, but when I try to move on to the next image in the album or in the "Unknown" people category.  I'm using Digikam 2.9.0 on Ubuntu 12.04.  I haven't been able to generate a backtrace so far, the only "inside information" I have is this:

*** glibc detected *** digikam: malloc.c:2876: mremap_chunk: Assertion `((size + offset) & (_rtld_global_ro._dl_pagesize-1)) == 0' failed.
/usr/bin/digikam: invalid fastbin entry (free): 0x0000000005d13d20 ***


Reproducible: Always

We needs a GDB backtrace to investiguate :

Comment 2 Micha 2012-09-20 20:56:34 UTC
Hi Gilles,
Thanks for the quick response!  I really appreciate it.
I installed the debug version (at 316MB it's a bit on the big side though) and generated a backtrace.  I was sure I was using 2.9.0 but it turns out that what's I have now is 2.8.0 - maybe it's got something to do with the big KDE update yesterday?  Anyway, I'll paste the backtrace.  Note that in this case, the crash came not when I was going from one image to the next (as I described previously) but while I was adding the tags.

So here's the backtrace:
Application: digiKam (digikam), signal: Segmentation fault
