User Feedback

I just opened the qgz project which I was working with yesterday with no problem (in the same version of QGIS). The crash happened immediately after start-up.

If I open QGIS directly, it opens without complains. When I try to open the project from the list of last projects, it crashes again. Other projects can be opened without a problem. From the file size, I suspect the project was badly saved in the last time and is corrupt :-( Anyway.. this should not shut the QGIS down, it should report the problem of corrupted file to the user instead (if this is the case). I am including the qgz.
