I am having a related issue in that trying to add a "related issue" caused the login dialog to pop and even it canceled logs the account out that was logged in. I am using todays svn and the ldap login for auth.
--------------------------------------------------------------------------------
It looks like it has something to do with one of these change sets based on the timing.

Yes these modifications are presumably at the origin of the bug, if ever.
--------------------------------------------------------------------------------
I had the error before it is modified
--------------------------------------------------------------------------------
Did you get the error just after you upgraded your version to 1.2.x ?
--------------------------------------------------------------------------------
Yes
--------------------------------------------------------------------------------
Then maybe you should check that your @application.js@ is up-to-date by clearing your browser cache.

I have the same problem, but not in Redmine.

I installed an plugin, and when I open the page in the plugin, I found this error.

anyone knows why? How to fix it?

Thanks.
