Bug#983753: ardour: sometimes can't be stopped while playing if midi tracks are used.

[Wolfram Wagner <mrthehowlingwolf@gmail.com>]

Package: ardour
Version: 1:6.5.0+ds0-1
Severity: important
X-Debbugs-Cc: mrthehowlingwolf@gmail.com

Dear Maintainer,

I run Ardour and record some midi tracks. After using those, the program can
get into a state that does not allow to stop the playing.

The workaround is to save the session and reload it.

This seems to be a known issue upstream and it is reported to be solved in at
least the nightly builds.
