[Bug 328318] [NEW] calling uuid inside fuse callback -> unmountable fuse for 5 mins

[Ludovico Cavedon]

Public bug reported:

Binary package hint: python-fuse

If I call uuid.uuid1() inside a Fuse callback, the next time I try to
mount any Fuse filesystem I get

fusermount: mount failed: Cannot allocate memory

and the attached kernel messages.

See also attached python test case.
Try to mount, umount and mount again.

I was not able to replicate it with a pure C code.
