Bug 51091

Version:           1.5 (using KDE 3.0.9)
Compiler:          gcc 3.2.1 
OS:          Linux (i686) release 2.4.19-rc3-ac4

search messages.
delete a folder with one of the found messages.
double click that found message.
crash boom bang

Can deliver backtrace with symbols if wanted, but I think this should
be easy to reproduce.

Using maildir format.

debug output:
