[Duplicity-tracker] [bug #13407] duplicity crashes on long path name

[heiko]

Follow-up Comment #5, bug #13407 (project duplicity):

Hi,

this problem still exists in duplicity-0.5.18. tested against directory
structur created with the perl command in #3

i tried to fix it (without beeing a developer ;)) and ended with this patch.
dont know if it really fixes the problem or if it does harm anything else. but
backup and restore with files copied to the deepest directory which was
created from the perl command works.

please don't use this patch until someone confirms that it does not eat your
cat ;)
