Summary: tarfile stops expanding with long filenames
Initial Comment:
The tarfile module fixes an issue with "Some old tar programs represent a directory as a regular file with a trailing slash.":
if tarinfo.isreg() and tarinfo.name.endswith("/"):
tarinfo.type = DIRTYPE
*After* that the full filename is composed. The chars >100 are stored in "prefix":
if tarinfo.type != GNUTYPE_SPARSE:
tarinfo.name normpath(os.path.join(nts(tarinfo.prefix), tarinfo.name))
So guess what happens if you filename has a / at the 100th character. Right, its considered a directory. Since directories have no data, the next metadata block is read from your file data which fails in various ways.
Patch attached.

Ok, from looking at the code it should work in Python 2.5. I shipped
around the Python 2.4 bug by creating a zip release instead of tar.
Pity that Python 2.4 is no longer maintained though. I guess we need to
bump Zope 3 pretty soon then :)

Did you also test Python 2.5? If this error occurs with that version too
(which it should not), please attach a small test tar archive to this
tracker item.
Python 2.4 is no longer maintained, sorry.
