[vdr] vdr 1.4.1: Confused after /video full

I am running vdr 1.4.1. Some days ago I found it running in the morning. It hadn't shut down after a recording. Trying a manual shutdown gave the error message:

"Recording in -244 minutes. Really shutdown?" (not this message exactly, but the German version). Pressing "OK" did not work, I had to log in to a console and to do a "shutdown -h".

Reason: /video was full, no recordings could be deleted, so VDR tried in vain again and again to start the programmed recording.

Shouldn't VDR stop its well meant but useless efforts at the latest if the event to record is over?
