Description Hugo Rito 2008-09-04 15:50:21 UTC 
Version:            (using KDE 4.1.0)
Installed from:    SuSE RPMs

In the dialog, used by "Find in Files" to specify the top folder to look at, if the selected folder is a remote one (FTP, SMB) or, for example, a local one like the "Trash", after clicking "Ok" Kate crashes with SIGSEGV.

Easy steps to verify:
1) Open Find in Files;
2) Bring the dialog to choose the folder;
3) Choose Trash on the left side of the dialog;
4) Click "Ok".

Indeed, probably the bug is outside of kate.
