Hi!

Sorry to bother you with my debugging stuff, but *this* bug 
drives me crazy 8-)

First of all: This is the bt from KSpread. You can trigger this
bug by...pressing "Open..." >:->

HINT: If you want to *work* with KSpread, just remove the
'kspread_csv_dia.desktop' file... (this hint is the reason why
I cross posted this to KOffice, btw)

Please note that this crashes during the resizeEvent. The thing I donīt
understand is that the QSplitter::resizeEvent() just calls doResize() and
nothing else. This doResize() is a private method of QSplitter. Now
please have a look at the address of the method (0x2). This is a bug I've
never seen before. Maybe one of you (gurus) can tell me what's going on
here.

Of course this bug is independent from my Qt version (last weeks :)

Werner, going slightly mad (Queen :)
