NPE when clicking any button on first screen

[rohieb]

After starting the jar file, or running the gradle wrapper, the main windows shows the screen about what is new in this version, along with two buttons, "Continue" and "Changelist". When I click either of those buttons, the application crashes with a NullPointerException:

$ ./gradlew desktop:run

BUILD SUCCESSFUL

Total time: 10.036 secs

I can remember that it didn't do this with the downloaded 0.3.x jars as well as the 0.4.1 jar until recently (I already played 0.4.1 before on this machine), so I figure it must be related to some update on my system, but I'm not sure how to debug this further. I tried deleting ~/.watabou/ as well as /tmp/libgdx* (in case this is related), but that didn't solve the issue.

I've actually just released 0.4.1a to desktop, do you get the same crashes on the latest version?

No, everything is fine, thanks! :)
