This should be fixed by this upstream commit: https://github.com/mmitch/gbsplay/commit/118ed43ae47c6db6b6aec57a4ecdafff8cb86abd
The fix is based on the error message, we did not set up an experimental Debian environment. version overview: - currently Debian unstable contains gbsplay 0.0.97 - gbsplay 0.0.98 was released just 2 days ago and is not yet packaged for Debian - the fix will be part of gbsplay 0.0.99, which has no release date set yet Regards Christian
