Bogus hobbitfetch reds and purples

[Hobbit User]

I have hobbitfetch working nicely for data fetching, but it continually
goes red, then purple, with a detail of "-Program crashed" and "Fatal
signal caught!".  When this  happens, it's still fetching the client data
without a hitch as far as I can see.  When I came in this morning, I had
the purple, with "Status unchanged in 0 hours 22 minutes", since I started
writing this, it's gone to red with "Status unchanged in 0 hours 3
minutes", all the while happily updating the client data.

hobbitfetch.log has 0 length and was last touched about four hours ago. 
hobbitlaunch.log says "hobbitlaunch.log:2007-06-04 08:34:22 Task
hobbitfetch terminated by signal 6".  The client data display available
through the hobbitfetch status page is stamped 8:32:35 and clearly shows
the hobbitfetch process running.

Clues?
