Comment 1 Remy Suen CLA 2012-02-02 10:46:25 EST 
Just run this code and it'll die.

---------------

Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new FillLayout());

CTabFolder folder =  new CTabFolder(shell, SWT.SINGLE); 

folder.setMRUVisible(true);
folder.setMRUVisible(false);
while (!shell.isDisposed()) {
  if (!display.readAndDispatch())
    display.sleep();
}
display.dispose();
Comment 2 Remy Suen CLA 2012-02-03 10:26:26 EST 
Please fix this for M6 as anyone that switches their theme before having any editors open will get this exception.
Comment 4 Bogdan Gheorghe CLA 2013-08-29 09:57:27 EDT 
Yup, should be fixed. 

Closing - please reopen if you are seeing this.
