Another bug in KDE MDI template app -> crash on file->openRecent ?!

[Maximilian Hrabowski]

Hi, again I'm not sure whether this is a bug in the KDE MDI template or in 
KDE3... (kdevelop 2.1 latest CVS, KDE3-beta2, qt3.0.2)

I simply created a new KDE MDI Application with the wizard, compiled it (BTW: 
for KDE3 you need to "#include" kurl.h,kstatusbar.h and kpopupmenu.h on top 
of "mykdemdiapp.h" into the template), ran it, opened three files to have 
something in the recent files list, quit. 
Then I restarted and opened one file after another from top to bottom with 
File->Open Recent. 
After having released the mouse button the third file loads as expected, but 
after that the application crashes ( output below ).
I think that the mouseReleaseEvent of the popupmenu sends a signal to an 
non-existent receiver...

for this never happened for me in other kde-apps so far, this is probably a 
bug in the template code (i was not able to reproduce this bug with a KDE 
Normal App).
