That is on purpose. If you give mathtext something that is a syntax
error, it throws an exception, showing where the syntax error occurred.
The only time mathtext gives warnings (as opposed to errors) is when a
the expression is syntactically correct but the symbols can not be found
in the currently configured font. This is to make sure that plots are
portable between matplotlib installations ... but the intention is not
to fail silently on invalid expressions.

That was an oversight -- and is a good idea. This has been added in r4586.
Thanks for finding this,
