[Bug 275157] New: Digikam crashes while removing tags from images

https://bugs.kde.org/show_bug.cgi?id=275157

           Summary: Digikam crashes while removing tags from images
           Product: digikam
           Version: 1.9.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Application: digikam (1.9.0)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:

I was in batch (multiple files selected), removing tags from images. The files
was a mix of jpg and dng files. The crash is not consistent (happens not
always). And the crash occurs after the tag has been removed from all the
selected images (checked that they were applied after re-opening Digikam).

The crash can be reproduced some of the time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault

Crash is not in digiKam, but in Oxygen theme engine from KDELibs (kstyle)...

The crash is in malloc, caused by memory corruption, which could have happened
everywhere.

If the crash is reproducible, please add a valgrind log, or exact steps to
reproduce. For more information, see

Yesterday it was reproducable (5 times ...) I've tried to reproduce it today
using valgrind, but helas; digikam did not crash once. I'll post a valgrind
backtrace if I get it again to crash. I did boot my pc since yesterday ...

Bart: It does not need to crash; reports about invalid memory operations (in
digikam code; there will be lots of others) is all we need
Also I recommend to try a 2.0 version, maybe the bug has just disappeared.

New digiKam 4.11.0 is available.

https://www.digikam.org/node/740

Can you reproduce the problem with this release ?

--- Comment #6 from Jeff Dooley <[hidden email]> ---
I've seen this crash many times. My current setup is:
Kubuntu 15.10, KDE Plasma 5.4.2, Qt 5.4.2, Kernel 4.2.0-22-generic
Digikam 4.12.0, based on KDE Development platform 4.14.13

At the dev's request, I installed digikam-dbg and valgrind via the Kubuntu
packages. Based on the reports below, it now appears that these crashes may not
have anything to do with digikam per se. If there is anything else I can do to
help, please let me know. Thanks.

--- Comment #8 from [hidden email] ---
Exiv2 library crash.

You must use Exiv2 0.25. libkexiV2 and digiKam need to be recompiled.

In Help Component Info, Exiv2 0.25 must be registered, not an older version.

If the problem still here with Exiv2, report to Exiv2 team.
