Description Telanos 2012-09-01 02:02:25 UTC 
Application: digikam (2.5.0)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-29-generic-pae i686
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
If a big Gimp image has been added to the collection since the last start, this can lead to a sytematic crash of the application when it starts.
The image that causes the crash was a 639MB xcf file of 25061x6963 pixels (174 Mega-pixel panorama).
Feel free to contact me for tests.
( IMG_7056-7093_03_Equirect_50pct.xcf )

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".

Comment 1 caulier.gilles 2012-09-01 05:31:45 UTC 
It crash in Qt image loader, not digiKam...

Comment 2 Christoph Feck 2012-09-01 14:35:51 UTC 
It crashes here:

/build/buildd/digikam-2.5.0/core/libs/dimg/loaders/qimageloader.cpp:117

(qBlue is only a macro)
Comment 3 Marcel Wiesweg 2012-09-01 19:35:49 UTC 
Agreed, crashes inside the QImage loader. Most probably, memory allocation fails for the large image (digikam does not support tiles). I dont know, though, why the safe memory allocation "seems" to work (we watch for std::bad_alloc)
Comment 4 Kenneth Ingham 2013-04-24 21:57:23 UTC 
I also see this behavior.
Comment 5 Kenneth Ingham 2013-04-24 21:58:40 UTC 
(In reply to comment #4)
digikam-3.0.0-1.2.1.x86_64 on OpenSUSE 12.3 patched as of today.
Comment 6 Kenneth Ingham 2013-04-24 22:20:13 UTC 
(In reply to comment #5)
Upgrading to digikam 3.1.0 resolved my problem.
