Comment 2 David Strupl 2012-10-15 09:13:56 UTC 
UndoRedoManager.setPerformingSaveActions is not ready to be called from different threads (as the exception report shows it is called from EDT and also from a RP).
Comment 3 Miloslav Metelka 2012-10-18 13:50:17 UTC 
The save actions are now executed together with the actual save in a single atomic locked runnable. UndoRedoManager was updated accordingly.
