Comment 2 for bug 255190

Sorry about this. There are some problems with the version of Jokosher in Hardy Heron. Unfortunetly we cannot get any useful information from the generic error in the screenshot you provided. However we are currently working to make it easier to diagnose these problems in the next version of Jokosher.

If you would like to attempt to debug this with our help come into #jokosher on irc.freenode.net, and we can show you how to get the detailed logs yourself.
