Thanks for your help :). I didn't know we could use '~user'..

In order to try all this I made a small script called /tmp/test.sh, and 
set up a cron job to have root launch it in one minute.
After a few tries, I found the script worked when it had these contents
----
#!/bin/sh
echo "launched" >> /tmp/test.log
su evan -c "GTK_IM_MODULE=uim DISPLAY=:0 XAUTHORITY=/tmp/.gdmorTQs8 \
/usr/bin/ssh-askpass Encrypted File System cryptkey" >> /tmp/test.log
----

There are still a few things that I don't understand:

First, my XAUTHORITY is not /home/evan/.Xauthority but /tmp/.gdmorTQs8 
There *is* a file /home/evan/.Xauthority but it is owned by root (maybe 
remaining from my configuration attemps). I will try to remove it and 
log out and log in again when I can.

Second, when I don't set the GTK_IM_MODULE environmental variable, it 
doesn't work and in /tmp/test.log I have the following line:

Launching a SCIM daemon with Socket FrontEnd...

This seems to be linked to the japanese langage configuration.
