scheduler plugin crash

[abubin]

I am using windows deluge 0.5.6.2b.

I only have torrentfiles and torrentpeers enable (it's default).

Then I enabled scheduler and did my scheduling. I left it overnight and went back. When I comeback to the office, deluge has crash and closed. So the crash most probably comes from the scheduler during the changing of the bandwidth time. Since it just closed, I can't see any error. Is there a log file that I can look for some errors for dev to debug?
