Comment 1 Dario Andres 2009-04-09 14:30:17 UTC
Here using:

Qt: 4.5.0 + qt-copy-patches-936035
KDE: 4.2.68 (KDE 4.2.68 (KDE 4.3 >= 20090327))
kdelibs svn rev. 949645 / kdebase svn rev. 949645
on ArchLinux i686 - Kernel 2.6.28.8

I can reproduce the crash.

Comment 2 Dario Andres 2009-04-09 14:43:44 UTC
Just wondering, the "/" shortcut ("Find as you type"), is disabled on the menu. But you can call it manually pressing the "/" key

I experienced the same problem under 4.2.2 installed from Debian unstable.
Comment 5 Allan Sandfeld 2009-04-14 21:02:17 UTC
Maybe inline '/' search should just be removed, since ordinary ctrl+f search is also incremental now. The duplicate code is just a source of bugs, and if we tie '/' to ordinary search the functionality is still there.
