The fix appears to be:

It looks like the reason there is not an error in later versions of Trac is the addition to the top of the function to handle a tuple argument:
{{{
#!python
    if symbols and not isinstance(symbols[0], basestring):
        symbols = symbols[0]
}}}

So the modification to the function call may only be necessary for Trac 0.11 compatibility."	defect	new	normal	AnnouncerPlugin	normal		i18n compatibility		0.11
