Udev is probably the wrong place to do this, since cryptsetup does some
udev magic to make it wait for all outstanding events.
And guess what: your script that ran from udev, that called cryptsetup,
is making one of those events stay outstanding. :-)
You might be able to change the rule, making it call your script
differently, but what I'd try is either (a) finding somewhere else to
hook this script in (not that I have any good suggestions :-( ), or (b)
trying to make the script fork and do the work in the background.

Doesn't your desktop handle automount for you when the /dev/mapper/*
device shows up?
