Forgot I was on the list, or I would have posted the original question myself. ;)

I tried your solution, but it didn't work...I'm still seeing the "not supported in font" errors.

It's not fatal in the sense that someone can still type in a full path to load a grammar, but it does break browsing the file tree in the load grammar dialog.

On further investigation, it looks like I introduced the problem on my Knoppix 6.2-based versions of the CD when I disabled prelinking.  (It was causing shared libraries to load lower in memory, blocking the LISP heap.)  It also didn't crop up on CDs I did based on Knoppix 6.0, which didn't use prelinking, so maybe I'm changing something else when I remove the prelinking info from the libraries.
