Ok, I have found the reason why the game doesn't start anymore. The config file of pink-pony in ~/.config was not upadated with the latest release. That means it contains outdated information about the location of the game data files.
Ideally the config file should have been recreated automatically and adjusted for the new release. Another option would be to create a NEWS file that mentions the change and asks the user to remove the config file manually. Please feel free to close this bug report because the old version 1.2 has never migrated to testing and only users of unstable are affected who had installed 1.2 before. Regards, Markus
