Silent Crashes

Hi,
I've been using Hazel for ages with no real problems but recently it's been crashing. After a few days running, all hazel processes terminate without warning. Quite often it'll be a few more days till I notice that the sweeping brush has vanished from the menu bar. Nothing in the logs, even with all DEBUG options turned on, but there are a couple of .crash files, one including this
Any suggestions what to do next?
Thanks in advance.
