Bug 282298

Summary: Digikam crash during startup (Digikam::ThumbnailCreator::loadFromDatabase fail)
Product: [Applications] digikam Reporter: Oldřich Jedlička <oldium.pro>
Component: Database-ThumbsAssignee: Digikam Developers <digikam-bugs-null>
Status: RESOLVED WORKSFORME    
Severity: crash CC: caulier.gilles, dilfridge, mbbdisposable-questions, vivo75+kde
Priority: NOR    
Version: 2.1.0   
Target Milestone: ---   
Platform: Compiled Sources   
OS: Linux   
Latest Commit: Version Fixed In: 2.2.0
Sentry Crash Report:

Description Oldřich Jedlička 2011-09-18 17:54:17 UTC 
Application: digikam (2.1.0)
KDE Platform Version: 4.7.1 (4.7.1) (Compiled from sources)
Qt Version: 4.7.4
Operating System: Linux 3.1.0-drm+ i686
Distribution (Platform): Gentoo Packages

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

Just started the application and it always crashes on the same place. From the stack trace there is one really strange point - the Digikam::ThumbnailCreator has the "this" pointer valid, but when calling loadFromDatabase it gets null. Either this is wrong gdb trace or it is really like that (other thread freed the ThumbnailCreator?).

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Aborted

Comment 1 caulier.gilles 2011-09-18 18:43:27 UTC 
Can you try again with 2.1.1 ?

Gilles Caulier
Comment 2 Andreas K. Huettel 2011-09-18 19:21:29 UTC 
Gilles: I have not packaged 2.1.1 for Gentoo, because it is identical to our last 2.1.0-r2 patch release. (Would be just a useless recompile for all users.)

Oldřich: is this digikam-2.1.0-r1 (=2.1.0) or digikam-2.1.0-r2 (=2.1.1) ?

Ah, sorry, I see from the backtrace. Definitely Gentoo digikam-2.1.0-r2 = upstream 2.1.1
Comment 4 Francesco Riosa 2011-09-19 18:08:14 UTC 
maybe re-emerge libpgf an posting here
emerge --info media-libs/libpgf 
just a wild guess
Comment 5 Oldřich Jedlička 2011-09-21 05:05:55 UTC 
I've updated the system (new libpng, so few rebuilds) and it works now. Thanks for help, anyway.
