Package: rdiff-backup
Version: 0.13.4-3
Severity: grave
Justification: renders package unusable


I have been using rdiff-backup for daily backups of a working directory
for a quite a while now. Recently it stopped working (I cannot say for
sure if it was after I upgraded to 0.13.4-3, but I think so).

I am backing up a subfolder of my ~ dir to a directory on another machine
mounted via NFS. I have rwx------ on the backup target directory. Now,
I keep getting crashes when rdiff backup starts (Traceback see below).

I have tried backing up to another local folder. That works fine.
I have tried to access the NFS folder not through the symbolic link in 
my ~, but through the path of the mount point. Didn't work either.

The strange thing is, I never changed the way I call rdiff-backup. This
was in a little shell script.

Kind regards


Andreas

> If this bug is unreproducible, should it also be downgraded?

I had planned on giving him two weeks from the date (Sept. 4) I last
sent the bunch of questions I hoped would help, but he hasn't replied
and I don't see any pressing reason to keep this open three more days.

Andreas said that things magically worked when he downgraded to the
ancient 0.6.1 in stable, which doesn't have the feature set that
appears to have triggered this bug, so that doesn't surprise me.

I'm going to close it - Andreas, if you can provide more information
on the questions I asked, I'd like to look into this more, but I
simply haven't been able to reproduce it and no one on the
rdiff-backup lists has reported a similar problem.
