I have found that in  DocTreeViewPart::~DocTreeViewPart(), if I remove the two 
following lines :

if (m_widget)

then it crashes latter :-( and I didn't go farther to find the other crash.

The crash in 


happens because the TopLevelMDI object used by topLevel() has already been 
deleted before.

If someone know how to make topLevel() safer then that would be fine. If not 
then we need to delete the two above lines.
