Incidently, I found attempting to log in to JGF crashed with an error report, which didn't tell me where to mail it.
Something in the last patches on Sunday is deeply wrong - generated > 15gb of logfiles in 2 days, ran out of disk space

. Trying to find out what's in there now, but 15Gb is not easy to examine

.
When I got back to the site I still could find an email address to mail the stack trace to?
Thanks, I'll add that to the todo list. The stack-trace-display is hard-coded (for obvious reasons) so I need to actually dig into code, but it'll be no problem.
