[Ardour-Users] crash with current git master

[Gunter Königsmann]

Dear all,

The current git master of Ardour6 was announced to be in development and
not being fit for production use. So if this crash is known no harm is done.

But if it isn't known: When seeking in ardour [alsa oudio, happens both
with stereo and 4ch projects] on Ubuntu I get the following:
