mastertickets.webui causes genshi traceback

[bernd.tegge@…]

When I enable mastertickets.web_ui on an OpenSuse 11.0 install I get the following traceback in my browser when I try to view a ticket.

Traceback (most recent call last):
  File "/usr/local/lib/python2.5/site-packages/Trac-0.11-py2.5.egg/trac/web/api.py", line 339, in send_error

According to the Genshi-FAQ this is ​not a genshi problem.

Versions: Python 2.5.2, Trac 0.11, Genshi 0.5.1 or Genshi 0.6dev_r914, MasterTicketsPlugin-2.1.2, postgresql 8.3.1.

An earlier install on a previous version of OpenSuse (Python 2.5.1, Trac 0.11, Genshi 0.6dev_r884, MasterTicketsPlugin-2.1.2, postgresql 8.2.6) did not show that problem.

Just an idea: As the computer (hopefully) uses utf-8 and locale de_DE-utf8 throughout the system could this be caused by umlauts from the error message caused by #2658 ?

ok, I've patched model.py according to #2658 (see below). This seems to fix the problem for me.
