There is a bug in webkit too for not showing an error message (for the
example used in Bug 530891):
runtime error: file avail-test.xsl line 14 element value-of
element-available() : invalid arg expecting a string
runtime error: file avail-test.xsl line 14 element value-of
XPath evaluation returned no result.

Thanks for your help.
