attic create fails with "assert segments[segment] == 0"

[martin-vi]

During an initial attic create the backup fails after a while on a ~300Mb file. The error is:

Traceback (most recent call last):

I tried to run the tests, they fail with the same errors, error log on pastbin. The setup is a arm powered nas with debian wheezy.

Thanks for the help.

One issue copy and pasted from above linked pastebin:

File "/usr/local/lib/python3.2/dist-packages/Attic-0.14_5_g4ab4ecc-py3.2-linux-armv5tel.egg/attic/testsuite/archiver.py", line 124, in create_test_files
os.utime('input/empty', (19880895600, 19880895600))
OverflowError: Python int too large to convert to C long

This is a 32bit platform issue and I fixed it by changing that line, see PR #254.

See also #309 for some already analyzed ARM issue.

@martin-vi Maybe add some more infos here (see what I requested in #309 and try whether it can be fixed in the same way).
