After upgrade to 6.5.4, data destroyed on remote and local: gmail drafts, sent, spam folders

[Christopher Barrington-Leigh]

I upgraded offlineimap through Ubuntu 12.10 and after fixing the cert problem, I let offlineimap do its thing.
It has deleted all messages in my Drafts folder, on both local and remote repositories.

It may have done other damage too; I don't know.

I believe that many folders which had been local but not on gmail (remote) were for the first time created on remote.
There are other problems as well (some new duplicate /weird folders created on gmail) that are hopefully separable from this reported bug.

Other damage: it is repeatedly destroying all the contents of my Drafts and my Spam folders, both on gmail and locally!

I'm attaching some output from offlineimap. There's a continuous section at the beginning followed by some grepped extracts.

I hope there's no compromising info in there...

I'm attaching
offlineimap --info

output, with some folder names removed.

My nametrans etc have not changed since before the upgrade.

Correction/update: all my sent mail (!!) as well as the spam, and drafts messages are lost and new ones deleted.

Workaround (?) to save your mail: uninstall offlineimap. Download offlineimap_6.3.4-1_all.deb (ie, the old version) from Ubuntu and install it, e.g. using the software center.
