Comment 1 Christoph Feck 2011-11-19 01:30:11 UTC 
What does ApperKCM::search() do that it could cause a crash inside the system settings list views?
Comment 2 Daniel Nicoletti 2011-11-19 02:04:05 UTC 
It's not system settings it's own categories view, this is a crazy random bug that I never see here, but some people have it tho I have no clue what happens on their system to crash like this..

From bug 289717:

"Applications inside software management needs only one click and I was double
clicking it, when I do this it crashes, but if I click once , wait , and click
again, then it doesnt crash.
I think there is already another report about this one."

Looks like something starts a local event loop, so that double clicking causes reentrancy bug.

apper (0.7.1) on KDE Platform 4.7.4 (4.7.4) using Qt 4.8.0
