Bug 69195

I cannot reproduce with KDE3.2cvs and KDevelop CVS.

As RMB-Menu->Application->close would not appear in the original Beta1, i assume you're using something more recent. Can you try with a kdevelop cvs checkout? A lot of bugs were fixed and some things changed with new KMDI.

Could you provide us that backtrace anyway?

I was using kdevelop cvs (sorry, I forgot to mention it). Updated
yesterday. So it might be kde3.1 specific..

This Bt is not very usefull.
Could you:
make clean
./configure --enable-debug=full --prefix=........
make
make install

And try again?

OK, I can reproduce it with KDE 3.1.3 and QT 3.1.2

But I see no KDevelop references.... it migth be a Qt bug.

Can not reproduce it again with CVS HEAD.
Please update and let us know if it fixed the bug for you.

Ok. Finally got around to install kde cvs, and it does not crash anymore.

So this bug can be closed.
