Deadlock in EAP 10 when doing code cleanup

I just want to do a  code cleanup for a file in a solution which is under TFS source control. It took a quite long while for a file with 10 lines of  code so i canceled the cleanup. But the dialog will not disappear until i fired off Visual Studio in the task manager,

The source file was write protected because it wasn't checked out. I can see the "Check out" dialog of Visual Studio but can't handle it, because the R# dialog prevents it.
