Judging from the backtrace, this seems like a duplicate of bug 255678. Was JuK scanning for music files when you closed it?
*** Bug 288836 has been marked as a duplicate of this bug. ***
Is there a reason for calling "processEvents()", which creates a local event loop? If you are displaying a progress dialog, and want it updated, you have to make sure the dialog is modal to the main window, otherwise the user is able to close the main window during the nested eventloop, causing this crash later.

(In reply to comment #4) Ah yes, I was trying to close juk when it crashed.
