I managed to get a backtrace when a crash happened:

  • Summary changed from Deleting a workspace or using clear memory option when a plot is open, can cause a crash to Deleting a workspace or using clear memory option when a MantidMatrix is open, can cause a crash

Note that this actually seems to be related to closing MantidMatrix objects rather than the plots, so I've changed the title
