I have a bookmark in Firefox pointing to https://SERVER/redmine/issues?query_id=4&per_page=100

If I am logged into redmine, this works absolutely fine. If I am not logged in to redmine, I would expect it to jump me to the redmine log-in page and once I've logged in it should take me back to the query page. What it does instead of this is report:

bq. Internal error

bq. An error occurred on the page you were trying to access.
If you continue to experience problems please contact your Redmine administrator for assistance.

bq. If you are the Redmine administrator, check your log files for details about the error.

bq. Back

The log entry is at the end of this bug report.
