[Duplicity-talk] duplicity fails on Debian (etch and lenny) - tempdir?

[Stefan Hoth]

Hello list,

my current version of duplicity stopped working a while ago. After
trying to upgrade python from 2.4 to 2.5 and some debugging I blamed it
on Debian Etch. Since I had planned to upgrade to Lenny anyway I didn't
waste more time on that issue.

So, after finally upgrading to Lenny a few minutes ago I was completly
bummed by the fact that the error still occured.

Since I don't have any more clue on how to fix this I turn to you guys.
Any help?

FYI: I now have duplicity 0.5.17 running on python 2.5.2-15 (Debian
Lenny package).

Here's the stacktrace:
