Edit options doesnt work in translated page

[Mbrix]

Hello,

When the language is set to Danish (havn't tested other
languages) and I click the button on the web interface
"Unsubscribe or edit options", I get this:

Bug in Mailman version 2.1.5

We're sorry, we hit a bug!

Please inform the webmaster for this site of this
problem. Printing of traceback and other system
information has been explicitly inhibited, but the
webmaster can find this information in the Mailman
error logs.

The backtrace from the error log looks like this:
