spins after signing message

Binary package hint: evolution

Occasionally evolution on Hardy (up to date) seems to spin after (trying to) sign a message with gpg. The UI stops painting so it's stuck in a tight loop somewhere.

The stack trace looks like:

The process list from evolution looks like:

 8095 ? Tl 2:51 \_ evolution --sm-client-id 110a4b1601000120007605900000271910021 --screen 1
11781 ? Zs 0:00 | \_ [gpg] <defunct>

So evolution is not even reaping the child process.
