[rdiff-backup-users] Exception exceptions.TypeError: "'NoneType' object is not callable"

[Gurvan Huiban]

Dear list,

in my lab, we use rdiff-backup (version 0.13.4, from Debian stable 
distribution) to make a daily backup of the home of the users. It was working 
fine until yesterday.

Yesterday, I deleted the account of a user. When rdiff-backup made its backup 
of the home directory, it returned some "UpdateError File changed from 
regular file before signature", as for instance:

============
UpdateError brut/.bashrc File changed from regular file before signature
============

Then, the backup started and rdiff-backup crashed (full message below).

From now on, if I try to run rdiff-backup again, it crashes the same way. I 
gave a look to the rdiff-backup wiki, especially this page
http://rdiff-backup.solutionsfirst.com.au/index.php/FileChanged
but as rdiff-backup crashes, the metadata files are not complete.

What should I do to make rdiff-backup work again? Why removing a directory 
make rdiff-backup crash so badly? How can I prevent this to happen again?

Thanks
