Package: openarena
Version: 0.8.8+dfsg-2
Severity: grave
Justification: renders package unusable
Dear Maintainer,
* What led up to the situation?
I attempted to launch the program.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Ran `openarena` from a terminal.
* What was the outcome of this action?
Program failed to launch with a lengthy error message (attached).
* What outcome did you expect instead?
I expected the program to launch normally.
