From bug 224156:
-- Information about the crash:
I installed 4.4 RC2 yesterday, and krunner already crashed twice. Once when I
was trying to start knemo (which turned out wasn't installed), and it kept
selecting a song in Amarok. The second time, I started entering systemsettings,
saw it guessing what I wanted to do, and pressed right arrow. I couldn't get it
to crash again like that.

Based on the old duplicates and the current lack of cases I'm setting this bug as fixed for KDE SC 4.5.x and later.
Thanks
