Again another crash -- with Qt 4.6.2 -- that should not happen if I understood 
everything correctly:

term.contains(QRegExp("^[a-zA-Z0-9\\-\\.]+\\.[a-zA-Z]{2,6}"))

http://websvn.kde.org/tags/KDE/4.4.2/kdebase/workspace/plasma/generic/runners/locations/locationrunner.cpp?view=markup 
line 99
https://bugs.kde.org/show_bug.cgi?id=247117

The code has changed since then (for KDE 4.6), so asking users to retry with a 
newer KDE version would not get valuable information.
Still I tried to reproduce the crash with the old code and with Qt 4.7.1 but 
was not able, so is that fixed there?
