Hi.
I've been digging into a bug for a few days, now. After upgrading from Debian
Sarge to Etch, our python application crashes (SEGV) if we install an event
filter.
Attached is a minimal example of the problem.
The application doesn't crash when commenting out the installEventFilter,
despite the fact it does nothing.
Does any one has a cue?
I suspect a problem in KHTML sending a signal to a deleted object.
It could also be that the void *data of the QCustomEvent causes problems in
sip that can't possibly convert its type...
Or maybe I'm just doing something wrong that will look obvious to an expert ^^
