*** Bug 123441 has been marked as a duplicate of this bug. ***
I cleaned up some static QString object in RSS::FileRetriever (using a static QString* instead), which can cause crashes on shutdown according to David. And I haven't had this crash for some time now. Maybe that fixed it, don't know for sure... Please report if you have this bug with SVN 3.5 branch >= 516072 or upcoming 3.5.2.
This should be fixed by now.
