Description jcb1985 2010-01-11 14:15:46 UTC

Application: digikam (1.0.0)
KDE Platform Version: 4.3.90 (KDE 4.3.90 (KDE 4.4 RC1))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-17-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
after having used the rotate tool, I tried to save the picture, Digikam asked me if I wanted to overwrite the original file, I clicked Yes, and it crashed.

Please note that I'm using Digikam 1.0 with Qt 4.6 from Kubuntu's beta ppa :
 https://launchpad.net/~kubuntu-ppa/+archive/beta/

The crash can be reproduced every time.

 -- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
The current source language is "auto; currently c".

Comment 1 Johannes Wienke 2010-01-11 15:59:20 UTC

Strange, in deep QCore crash. Could this be related to the malloc check stuff?

Comment 2 caulier.gilles 2010-01-11 16:47:04 UTC

Yes, certainly...

Gilles (which doesn't understand why libc exception have been enabled in KDELibs...)

Comment 3 Johannes Wienke 2010-01-11 16:54:12 UTC

Can you check if digikam still crashes if you

1. open a terminal
2. type "export MALLOC_CHECK_=0" + enter
3. type "digikam" + enter

Comment 4 Johannes Wienke 2010-01-11 16:55:06 UTC

Or maybe "export MALLOC_CHECK_=" without the 0.

Comment 5 jcb1985 2010-01-11 19:21:29 UTC

I tried both export MALLOC_CHECK_=0 and export MALLOC_CHECK_=
it crashed both times. 

note that sometimes the first picture modifications saving works, but it always crash with a second picture modifications saving

Comment 6 Johannes Wienke 2010-01-11 19:24:59 UTC

But the backtrace you gave us is not from a crash while saving a picture. The crash you reported must have happened directly after starting digikam, probably even before you saw any window. Can you give us another backtrace when digikam crashes while saving an image?

Comment 7 jcb1985 2010-01-11 20:00:15 UTC

I can assure you that I can use digikam without a single crash for hours!
It ONLY crashes when I edit a picture then save it. 

I'll give you a another backtrace in a few minutes

Comment 8 jcb1985 2010-01-11 20:04:42 UTC

Created attachment 39787 [details]
New crash information added by DrKonqi

the new backtrace you asked, occured when saving after editing a pic

Comment 9 Johannes Wienke 2010-01-11 20:19:16 UTC

Has anyone else got an idea what this could be? Looks completely strange.

I would suspect a problem with your Qt installation.

Comment 10 jcb1985 2010-01-11 20:31:12 UTC

could it be related to Qt 4.6 ? digiKam has been compiled with it in this ppa.
or because of KDE 4.4 RC1 ?

Comment 11 Marcel Wiesweg 2010-01-11 20:50:41 UTC

KDirWatchPrivate::Entry::findSubEntry (this=0xe32530)
at ../../kio/kio/kdirwatch_p.h:161

I would suggest a kdelibs (KDirWatch) bug.

Comment 12 Christoph Feck 2010-01-18 00:56:53 UTC


*** This bug has been marked as a duplicate of bug 222974 ***

Comment 13 caulier.gilles 2017-08-08 11:42:00 UTC

Since digiKam 5.0.0, KDirWatch was been replaced by QFileSytemWatcher. It will
not reproducible.
