[Kst] Segmentation fault / kst2 startup

I don't exactly know why but on two very different Linux machines
(openSuse 11.2 64 and Suse 10.0 both 64 bits, both Qt 4.5.3) I get a
crash on startup with the latest kst2 trunk.

I don't even get to see the main window :-(

I tried going back in time (and doing a clean build at each step
otherwise I was seeing strange things) and the commit that breaks things
seems to be #1054888 (the big update commit)...


Below is a backtrace:

Does anyone else also see that? It makes working with kst2 pretty
