1) Create in the inbox the following messages:
A 2Kb
B 2Kb
C 3Mb
D 2Kb

2) Fill the disk leaving just 2Mb free

3) Move the above messages to another folder (eg. Sent)

4) Thunderbird shows a message saying there wasn't enough space to move them

5) The state is now this:
Inbox: A B C D
Sent: A B

(messages became duplicated)

Given that the desired state is unreachable, it should be left in either:
Inbox: A B C D
Sent:

or

Inbox: C D
Sent: A B 

Note that even a check for free space before actually doing anything would help. It could still happen, but would need a race condition.
