Comment 14 for bug 261595

This problem is also true for NNTP.
I subscribed to several hierarchies on 2 newsgroups servers in my thunderbird and at some point, I closed thunderbird while the disk was out of space.
Then, when I started it again, on one of my 2 NNTP accounts, all the groups I had subscribed had disappeared.
The files corresponding to these groups are still there in my profile account but it seems that thunderbird has no idea of them anymore.
If I try to subscribe again to these groups, It seems that thunderbird don't retreive the old informations it had on them, like read articles.
