Affects: gimp (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
In Breezy:

If the gimp swap-dir is set to some invalid location, and a large file
is opened, gimp starts generating warning dialogues at a rate of several
per second. Soon Xorg is overwhelmed,  all memory seems to be eaten, and
C-A-backspace is needed.
