No one seems to have picked up the glove, so here I go (since I use
Excalibur quite extensively): your sample works OK if you set not to
use "LaTeX -> Warn on parsing errors" (in the preference pane), but
if the setting is on, Excalibur stops with the message "Excalibur
stopped processing on line 7 because of a LaTeX error. Extra } or
\end", and after a while it takes quite a bit of cpu (doing what?).

So indeed there is something similar to a bug, but you can avoid it
by changing the "Warn on parsing errors" setting. I am not sure on
how useful this setting is (if the file has compiled correctly, why
bother?)

All the best,

Nestor
