The <font> tag, like the <b>, <i>, and <u> tag are features of Reportlab's 
paragraph implementation. The <title> tag is just a special case of a 
paragraph.

So it should probably be considered a documentation bug that those 
paragraph-internal tags are not in the reference.

Further, I think the <font> tag was new in ReportLab 2.0 or 2.1.

No, because the 'fontName' can only set the font for the entire title and not 
just a sub-string in the title.

Okay, what OS are you using? Is it still occurring?

No this is because ReportLab is not thread-safe. Heck, it is not even safe to 
run multiple renderings in the same Python session. The level 2 tests show 
off a solution that solves this problem by starting a new sub-process for 
each rendering.
