Ardour crashes when changing tempo

So the Ardour 2.4.1 update is consistently crashing when I try changing the tempo of a session (not an add new tempo marker, the Edit of the session tempo). Freezes briefly, then crashes. Don’t know where I need to go for the full info of the crash, but the report said this, along with a bunch of other mumbojumbo three miles long:

I’m running the native osX on an intel MacBook Pro, 2.4ghz cpu, 2g ram, etc. I’m probably not providing all the useful information needed, so let me know what else I can provide to help (and how to find it). Thanks.

Done and done. Thanks for the info.

your bug report should include the entire crash log.
