full thread-dump (generated by JVisualVM)

I selected a directory node in the Favorites view and selected CVS > Revert Modifications. The IDE froze almost immediately. Later I found that modified files got reverted back to their base revisions (correct) and new files were not deleted (I do not know whether this is considered correct or incorrect).

I am not sure about which module contains the bug - reassign as needed.
