[TW-1393] Database corrupted after running task if the disk is full

I've run task to see my "next" list. It printed it fine.

I run it again to mark some task as done, but this time I got a strange message:

Taskwarrior no longer supports file format 1, originally used between 27 November 2006 and 31 December 2007. in /unfa/.task/pending.data at line 80

What happened? This is my theory: task tried to rewrite the pending file to update my tasks, but instead of rising an exception and halting the procedure, it wrote only a part of the file, because the disk was nearly full.

I think this behaviour is highly erroneous and causes severe data loss, where it can easily be avoided.
