[Duplicity-talk] Problem restoring files: AssertionError: 2

[Grégoire Détrez]

Hi,

I have troubles restoring files backed-up with duplicity. The restore 
operation crashes with an obscure error message:
> AssertionError: 2
I tried cleaning the backup using 'duplicity clean' and removing the 
local cache but the error is still there. I added some print statements 
to the code to try and figure out what file was causing the problem (it 
is some file created by git) but the '--exclude' option doesn't seem to 
work on restore. And the '--ignore-errors' option doesn't work either in 
this particular case.
I pasted the full traceback at the end of the message.
I found out that the problem is caused by the following data:
> [(('FETCH_HEAD',) None), (('FETCH_HEAD',) reg)]
which, since the first element is not 'reg', should have length 1 and 
not 2. But I'm stuck here because don't really understand what this 
correspond to…
Is there someone who had encountered this problem before?
I tested it with the code from the bzr repository so it doesn't seem to 
be fixed.
Otherwise, is there a way to tell duplicity not to restore a particular 
file?
Thanks,

Grégoire Détrez
