Description Thibault Godouet 2011-12-14 22:29:40 UTC

Application: digikam (2.1.1)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
1) I changed the video import filter to include .MTS files (with the appropriate the MIME type)
2) I started the importation tool, for pictures/videos taken with my Sony DSC-HX5V
3) I selected the filter "videos": Digikam crashed.

This is on Ubuntu 11.10

Comment 1 caulier.gilles 2011-12-14 22:34:13 UTC

Sound like a crash in KDELibs about typemime management. Not reproducible here.

Gilles Caulier

Comment 2 caulier.gilles 2011-12-18 13:54:36 UTC

Thibault,

Can you reproduce the crash with last 2.4 ?

Gilles Caulier

Comment 3 Thibault Godouet 2011-12-18 23:00:47 UTC

Hi Gilles,

As far as I know my distribution (ubuntu 11.10) doesn't have a package for Digikam 2.4.
Compiling it myself will probably be tricky, especially as I would expect my distribution not to have the right KDE library versions.
Do you have any suggestion as to how I can test this with digikam 2.4 easily on my distribution?

Regards,
Thibault.

Comment 4 Thibault Godouet 2011-12-21 09:16:29 UTC

Hi,

I ran a nightly build of the ubuntu 12.04 live CD, and installed digikam 2.4 in there to test: it doesn't crash.
However I can reproduce the crash with my digikam 2.1.1. If you can't reproduce it then it may be something on my SD card that triggers the crash. It's a big one (16GB) with personal pictures so I can't send it to you, but please let me know if I can do anything else to help you get all the information you need to locate and fix this bug.

Thanks,
Thibault.

Comment 5 caulier.gilles 2011-12-21 09:34:31 UTC

Thanks for the feedback. Crash have been fixed with 2.2.0 release.
