[DRE-maint] Bug#804805: Exception caught while uploading mail: File exists

[Antoine Beaupré]

Package: feed2imap
Version: 1.2.3-1+deb8u1
Severity: normal

I suspect this is similar to #590276 and #732297, but since the
backtraces are different, it could, actually, be a different bug.

I sometimes see this error in my cronjobs:

It looks like the file is already present, and indeed
/home/anarcat/Maildir/.feeds.git-annex/new/1447254884.0.marcos is
currently present. Why should this be a fatal error? Why not simply
recover and ignore that feed item?
