Yes, I've been hitting that one too, since we upgraded to Qt 2.1 final :(

The bug seems to be either in Qt (the QLayout code) or in KTMLayout.
The relevant konqueror code hasn't changed, and commenting out the dummy widget
in konq_viewmgr.cc's constructor fixes it - but since KOffice uses the same
'dummy' widget and works fine, it should work in konqy too.

Can someone with knowledge about KTMW's layout code have a look ?

I tried to look into it, but can't see what's wrong.

When the crash occurs, the kmainWidget member in KTMW seems to be a dangling pointer,
no idea why.
