[Duplicity-talk] (B2) FatalBackendException: Bucket cannot be created

[MRob]

Hello,

Been getting this for some while--
FatalBackendException: Bucket cannot be created

Bucket does exist and was happy being used for backups for a year 
previous. Error now happens on all actions, cannot access bucket to do 
anything at all. Funny thing but I didnot change my version or update 
software packages but B2 said they have no problems either so I'm not 
sure what really change to cause this. I can't find only a single 
refernce to this error on the web promising a fix in new version (of 
duplicity?)

Getting desperate I try just set up a new empty bucket but same error. 
So duplicity can not talk to B2 any longer. Can anyone help?

v0.7.06 (best available from apt-get)
