[Evolution] Mail lock file for local delivery?

["Peter.OShea" <peter oshea analog com>]

I've been using 1.3.92 and have had no problems until last week, when it
stopped retrieving mail.  I'm using "Local delivery" with mail delivered
to the system file /var/mail/$USER.  I don't know what triggered it, but 
evo stopped  pulling mail from /var/mail/$USER.  I tried switching account 
types to "Standard UNIX mbox", and evo then sees what's in /var/mail/$USER, 
but doesn't move it.

Is there some sort of mail lock file that could be present, keeping evo
from moving mail from the system mbox file?  I tried deleting the
contents of .gconf, .gconfd, and moving ~/evolution out of the way, 
then restarting gnome and evo - no success.

This is evo 1.3.92 compiled from source on a sparc Solaris 8 box with
gnome 2.3.  Thanks for any help.
