Thanks, Igor. It may just be to do with copying and pasting to the
mailing list, but your URL is actually different - the problem section
is not URL encoded ('JEzKjKps+0/AynL0G17OWg' instead of
'JEzKjKps%2B0%2FAynL0G17OWg'). It appears to be the URL encoding which
is actually causing the problem.
I'll try setting the log as you suggest.
