Summary0010290: Crash when adding both Tempo & Time Signature after BBT Marker
DescriptionArdour crashes with a segmentation fault when you try to add both a tempo and a time signature after having added a BBT marker. Adding several tempos or several time signatures works fine, but as soon as you try to do both (in whichever order), the crash happens. The reverse is also true if you try to add a BBT marker in front of an already added tempo and time signature.
This can be reliably reproduced from a brand-new empty session. I’m pretty certain that this bug is new to Ardour 9 (with 9.2 being the first minor version I tried).
Steps To Reproduce1. Add BBT Marker somewhere
2. Add New Tempo after BBT Marker
3. Add New Time Signature after BBT Marker

OR

1. Add New Tempo somewhere
2. Add New Time Signature somewhere
3. Add BBT Marker before both
