/usr/X11R6/lib/X11/XErrorDB exists on my system but there is no XtErrorDB file
at all.

Can you tell us which locale settings (LANG and LC_* environment variables) 
you're using ? This seems relevant to me.

It looks like it's related, yes. 

OTOH, the missing XtErrorDB file is probably not related. All Xt based 
applications behave this way...

i have those 2 lines for other X apps
(viewres/xcalc/xclipboard/xditview/xfontsel/xman), but xedit is the only one to
crash

look at this comment for what Rolland Mainz had to say about them :
http://freedesktop.org/bugzilla/show_bug.cgi?id=1325#c9

Is this still an issue using a current version of xorg?

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.

closing as worksforme.
