Bug 289797

Application: dolphin (1.99)
KDE Platform Version: 4.7.95 (4.8 RC1 (4.7.95) (Compiled from sources)
Qt Version: 4.7.4
Operating System: Linux 3.1.0-gentoo-r1 x86_64
Distribution: "Gentoo Base System release 2.0.3"

-- Information about the crash:
I couldn't find any duplicates, where the description pointed to exactly the same behaviour or the backtrace followed the same code path. Please mark as DUP if I missed one.

- What I was doing when the application crashed:
I'm now able to reproduce it in most cases using the following steps:
1. Open Dolphin
2. Set zoom level to minimum
3. Open a directory, which contains a lot of subdirectories containing a lot of images (e.g. Digikam collection directory)
4. Zoom in (using Ctrl+Mousewheel) while Dolphin loads the directory preview icons

This makes Dolphin crash here every 2nd try. I think it is important to reproduce the crash, that the previews aren't cached yet and need to be regenerated from crash.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Dolphin (kdeinit4), signal: Segmentation fault
