Warning message for every volume using --asynchronous-upload

[Daniel Andersson]

Using the --asynchronous-upload switch, the error message

Exception AttributeError: AttributeError("'_DummyThread' object has no
attribute '_Thread__block'",) in <module 'threading' from
'/usr/lib/python2.7/threading.pyc'> ignored

is thrown to STDERR every time a volume is created.

(I also used the -v5 switch)

Also reported as Debian bug #659004, but it has gotten no attention for a month.

There looks like there's a fix for this upstream, it just hasn't made it to the distribution yet.

My Apache2 logs are filled with the following error kicked out by my python wsgi script:

[Wed Mar 14 18:16:38 2012] [error] Exception AttributeError: AttributeError("'_DummyThread' object has no attribute '_Thread__block'",) in <module 'threading' from '/usr/lib/python2.7/threading.pyc'> ignored

I was able to silence these with a simple conditional in /usr/lib/python2.7/threading.pyc:

- del self._Thread__block
+ if hasattr(self, '_Thread__block'):
+ del self._Thread__block

Full patch attached."""

I'm experiencing this as well, though it is not fatal in this case. I can readily observe the difftar being uploaded.

I'm seeing this exact same error in duplicity 0.6.18 running on Ubuntu 12.04 after starting a fresh install and a fresh backup set.

I also see a couple of other error messages such as:
Cleanup of temporary file /home/Backups/.duplicity_cache/f8b8ad7f550c05bc2f127fe057fa58a5/duplicity-QysQAI-tempdir/mktemp-1PdBc8-1 failed
Cleanup of temporary file /home/Backups/.duplicity_cache/f8b8ad7f550c05bc2f127fe057fa58a5/duplicity-ekKsvE-tempdir/mktemp-BY_STs-1 failed

Please help, the backups claim to finish successfully, but it is hard to trust a new backup set/system if the first log is all dirty with errors.
