Conveniently, this happened again, today.
Here are the last, relevant bits from the
debug output on the console, including some
lines of output that were written AFTER I
killed the hanging process. (A few email
addresses and paths have been redacted.)

As you can see from the time stamps, the
process had been spinning for about 40 
minutes, before I noticed (and killed it).

The claws.log file did not seem to contain 
any additional relevant info. I have the
output saved, if you need more, let me know.
But this seemed to be the relevant bits.

Here goes:
