[zope2-tracker] [Bug 1479268] [NEW] TarballImportContext crashes when comparing the last char of empty strings

[Tobias Herp]

Public bug reported:

Products.GenericSetup, v1.7.6:

In Products/GenericSetup/context.py, there are two comparisons of
path[-1] to ‘/’, which must fail for empty strings (which are apparently
a known special case). IMO, here the endswith method must be used.

The empty string seems to be a known special case for tarballs.

I attached a patch.
