Hmmm... I cannot reproduce it.
Are you dealing with raster layers? Doing something fancy when exiting like leaving the add feature map tool in an unfinished state?

If you have a second to compile, can you patch src/gui/qgsmaptoolcapture.cpp and add a safety check at line 385:

if ( currentVectorLayer() )
currentVectorLayer()->triggerRepaint();

• status_id was changed from Open to Feedback

I just start QGIS and then quit it.

Your patch fixes the crash here. Thanks.
