Bug 232957

First you use digiKam 1.0.0-beta5. It's not maintained. update to digiKam 1.2.0.

Second, crash sound like located to Exiv2 library, not digiKam...

Gilles Caulier

Standard question for exiv2 issues is: Can you reproduce this with the exiv2 command line tool? If so, please provide the image that triggers the problem.

(The crash actually happens in a function called _wordcopy_fwd_aligned, which is not part of libexiv2. After scanning roughly 40,000 images...)

Thanks,
Andreas

Hello Andreas

and also Gilles Caulier

Thank you for the quick response. This bug is most probably related to 
the old release of DigiKam that is the default in Ubuntu. After 
upgrading to 1.1.0 the crash did not reappear. So from my point of view, 
the bug is resolved.

Regards
Stefan

I am also affected by this bug. My photo library is fairly large (approx. 100GB) and digikam has been crashing every time on startup.  It seems to be related to exiv2.

Here is the trace. Symbols were not available for exiv2 so I could not use the automated crash reporter.  I am running Ububtu 10.04 x86 on an HP Pavillion dv4-1413la with an Athlon X2 processor.

Application: digikam (1.2.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Crashes on startup every time.

The crash can be reproduced every time.

 -- Backtrace:
Application: digiKam (digikam), signal: Bus error

Sam,

update Exiv2 library to 0.20, recompile (or update) libkexiv2 and try again

Gilles Caulier

This is a crash in Exiv2 library.
digiKam 5.7.0 we use last Exiv2 0.26 where this crash must not reappear.
