Bug#546837: More debug

[Dominique Brazziel]

	Things keep getting odder and odder with this text parsing.
match_suffix.get_text(end) returns u'NNNNNN', where 'NNNNNN' is the
bug number, but when the string is appended to the url_prefix,
the 'u' appears in the first position of the array.  Both cases
the 'u' is unquoted:

[   DEBUG:UpdateManager.Util.procesinfo] url_prefix is
'http://bugs.debian.org/'
[   DEBUG:UpdateManager.Util.procesinfo] match_suffix = <GtkTextIter at
0xa620018>  match_end = <GtkTextIter at 0xa620050>
[   DEBUG:UpdateManager.Util.procesinfo]
match_suffix.get_text(match_end) returned u'531668'  <== u before bug #
[   DEBUG:UpdateManager.Util.procesinfo] url after appending
match_suffix.get_text is u'http://bugs.debian.org/531668'  <== huh?

Is the u some sort of attribute, for instance denoting underline?
