One of our tracker users tried to submit an issue with
a due date (DateHTMLProperty) set to *asap* (not really
a due date if you ask me). As expected, RoundUp didn't
accept it, but unfortunately doesn't it give an error
message in the *error_message* block (the red error
bar), but it came with a *Templating Error* (see below).
Wouldn't it be nicer if the date format error was
displayed in the error message block?

FYI:
On the server where the problem occurred we use roundup
release is 0.7.9 with python 2.3.3 on Linux.

Templating Error
