Thanks for your bug report. This bug has been reported to the developers of the software. You can track it and make comments here: http://bugzilla.gnome.org/show_bug.cgi?id=484797

Question from upstream:

"Is the crash reproducible? I cannot reproduce it here. If it is, could you
provide some more info from gdb, please?

In particular, after the capplet crashed:

(gdb) up
(gdb) print *a
(gdb) print *b

would be interesting to know."

The crash is reproducible with the method described above.

I forgot to mention, that the error occurs not only when i change the icons but also the border and the look of the buttons (dont know the correct names at the tabs, in german it's 'Symbole','Fensterrahmen','Fensterinhalt', sry).

Sorry for the unnecessary comment.
