Sorry, markup ate things.Let's try escaping ... HTML pages with MathML containing <mo>*</mo> with * = one of ( , ) , [ , ] , { , }

And the dirty workaround: changing <mo> to <mo stretchy="false"> avoids crash.

The problem dissapears after installing MathML suitable fonts. Playing with SeaMonkey Composer Math insertion, saw undefined symbols (weird squares), suggesting a font problem. Googled and found instructions here: https://developer.mozilla.org/en-US/docs/Mozilla/MathML_Project/Fonts Installed:...

Using Windows XP. May be newer Windows versions include suitable fonts by default. And some software like Office could install them too.(I dont have Office)
