We are glad to announce that RubyMine has recently changed bugtracking system to http://www.jetbrains.com/youtrack/index.html
Old Jira tracker works in read only mode now.
YouTrack is a brand new issue tracking system developed here in Jetbrains and its common workflow differs from good old Jira.
Please visit to get started: http://www.jetbrains.com/youtrack/index.html. Here you can find some tutorials on YouTrack itself.
RubyMine issues home page has already changed and can be found at: http://www.jetbrains.net/tracker/issues/RUBY
Update: For sure you can your Jira accounts for login to YouTrack!
