Description Jiri Klement 2007-01-18 08:01:59 UTC 
Version:            (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc 4.1.1-3 
OS:                Linux

Searching in documents (tested with pdf, chm and odt) always cause segmentation fault. Find dialog is correctly displayed, but after click on OK, okular crashes.

Backtrace from gdb:
Program received signal SIGSEGV, Segmentation fault.

Tested with qt 4.2.2 and current kdelibs from svn.
Comment 1 Albert Astals Cid 2007-01-18 21:03:52 UTC 
SVN commit 625053 by aacid:

okClicked is emitted by KDialog and this slot is connected to it, so if we emit it from there we end up in a infinite loop and we crash.
