Description mark 2010-02-12 12:05:54 UTC 
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.

Comment 1 Dario Andres 2010-02-12 13:14:08 UTC 
- Which other tags do you have ?
- Are you using Virtuoso 6.1 ?

> - Which other tags do you have ?

I have 4 tags: "Demotivator", "Hintergrundbild", "sinfest", "xkcd" :-)
I now touch'ed two empty files 'a' and 'b' in my home and the crash happens with every tag as soon as I try to tag the second file, so I guess it's independent from the content and the tags (names, order) itself.

> - Are you using Virtuoso 6.1 ?

yes, I am using virtuoso 6.1.0
Comment 3 Dario Andres 2010-02-12 13:34:52 UTC 
I could reproduce the bug here using:

Qt: 4.6.1 (kde-qt master commit 46ef51d8bf520bda3eea9e996349694ce1ff3959
        Date:   Sat Jan 30 02:23:21 2010 +0100)
KDE Development Platform: 4.4.63 (KDE 4.4.63 (KDE 4.5 >= 20100209))
kdelibs svn rev. 1088295 / kdebase svn rev. 1088295
on ArchLinux i686 - Kernel 2.6.32.3

Using two empty files (created with touch) and some already-existent random tags..
