Bug 226509

Application: dolphin (1.4)
KDE Platform Version: 4.4.00 (KDE 4.4.0) (Compiled from sources)
Qt Version: 4.6.1
Operating System: Linux 2.6.32.7 x86_64
Distribution: "Gentoo Base System release 2.0.1"

-- Information about the crash:
I have the following scenario:
1) open dolphin
2) open a folder with mostly picture files and other stuff (several formats like png, jpg, svg, html, txt, pdf)
3) move mouse over one picture that has no metainformation, add metainformation on the right side of dolphin (e.g. "wallpaper")
4) move mouse to the next picture without metainformation and try to click the metinformation link on the right side...
=> dolphin crashes (see included backtrace)

I repeated this several times with several picture files and it happens every time.
I did not try this with other files, because I wanted to reproduce it consistently.

The crash can be reproduced every time.

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