Description Ondrej Cernos 2007-11-03 19:12:55 UTC
Version:            (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc (GCC) 4.1.2 20061115 (prerelease) (SUSE Linux) 
OS:                Linux

kfind crashes when the find is stopped via the "stop" button.

The button has to be clicked twice, the first click is not respected.

To reproduce:

1. run kfind
2. search for some large file set (like *mp3 in big mp3 directory)
3. click "stop"
3a. optionally wait to see the find process did not stop
4. click "stop" - crash
Comment 1 Ondrej Cernos 2007-11-10 12:16:41 UTC
After a week, it seems the point 3a is not true any more - the find stops - but it still crashes when "stop" clicked for the second time. Backtrace follows:
