I just encountered this bug on 4.8-STABLE as well.
Trimming down the output of tset, I eventually
came up with the following very short test
case for tcsh:

# echo '{['
{[
# eval `echo '{['`
Missing ].
# eval `echo '{{'`
Missing }.

The problem seems to be triggered by a
{{ or {[ within '' within ``.  (The termcap entry
for vt100 contains {{ in the ac capability.  Removing
that capability is a workaround for this bug.)
Hope this helps someone to track the problem down.

For the record:
# uname -spr
FreeBSD 4.8-STABLE i386
# echo $version
tcsh 6.12.00 (Astron) 2002-07-23 (i386-intel-FreeBSD) options 
8b,nls,dl,al,kan,sm,rh,color,dspm,filec
