I think that unlikely; the spelling of space in that error message is
"space", not " ".  (Try C-c SPC or C-x SPC with debug-on-error
non-nil, they're usually unbound.)  There could be a deeper problem in
XEmacs that causes this symptom, but with XIM all bets are off, magic
is loose in the world.

Remember, XIM means that what you type is *not* what XEmacs gets, and
Asian typography has a number of different spaces (most Asian coded
character sets provide at least U+3000 IDEOGRAPHIC SPACE as well as
U+0020 SPACE).  The question is "If I'm right, what is XIM sending to
XEmacs that isn't an X keysym?"
