[reportlab-users] Bug in Paragraph class with tags when switching frames

I found the bug related to this in my code. Apparently, assigning styles
in OpenOffice docs (and I guess this is true for other editors as well)
to parts of a paragraph can lead to leading or trailing blanks being in-
cluded in the styled text (like a URL), e.g.

   spam www.foo.com eggs

becomes "tokenized" like this (simplifying a lot):

   "spam ", "www.foo.com ", "eggs"

which my code transformed mindlessly into:

   "spam ", "<a href='www.foo.com'>www.foo.com</a>", "<a href=' '> </ 
a>", "eggs"

so there was an undefined link destination.

I think it might be useful and possible to have better hints in  
exception
messages as to what is actually happening and which link destination is
failing.

Thanks and regards,

Dinu
