Game hangs when I enter the menu during demo playback

I'm using latest master compile (commit 38875273) on Linux.

If I record a demo (e.g. eduke32 -v3 -l6 -s3 -r) and then play it back (e.g. eduke32 -d edemo001.edm) and enter the menu by pressing Escape the game hangs.

Only happens with demorec_diffs 1
