[Bug 524243] [NEW] Python-boto crashes with Duplicity and Amazon S3

[Andrew Simpson]

Public bug reported:

Binary package hint: python-boto

Using Duplicity to back up to Amazon S3 with Karmic.  Having been using
this back up method for long time (more than one year), but has suddenly
stopped working in the last few days.

Can verify the problem on another machine with clean install of Karmic.
A Debian Stable machine on same network works with Duplicity + Amazon
S3, ruling out network problems.

Installing latest Duplicity from source made no difference.

Installing newer python-boto from Lucid (Python-boto-1.9b-
1ubuntu3-all.deb) fixes the problem.
