Nope, the issue with logging in isn't mentioned on github anywhere. All I get is an error occurred when logging in from google chrome and my blackberry's webkit browser. Disappointing.
Maybe you should submit a new issue?
P.S. I log in with chromium just fine. (Maybe you're entering your pwd wrong? Because identi.ca doesn't say "wrong password", but "an error occurred" in this case.)
I did enter my password correctly 20 times, even pasted it into the form from gedit and leafpad, same thing. :/
