#45 "Duplicate Internal Name" error thrown

[Michail Pappas]

Thunderbird: 6.0.2 on Windows 7 64-bit (same problem on Windows 7 32-bit)
Mozbackup 1.5.1

I used mozbackup to get backups of thunderbird (TB) when upgrading windows, or when I got a laptop. It worked flawlessly up to a specific TB version, which I do not recall.

Now I have to reformat my main rig due to a different motherboard. Problem is that when I ran mozbackup on my current installation, it throws a "Duplicate internal name" error, followed by a "Backup file isn't valid. Is this a MozBackup issue? Any workarounds?
