Summary0001913: crash while trying to move a newly created 'tempo marker'
Descriptionsimply to reproduce:

-create new session
-create new tempo marker (i did at about 5. bar, with 140bpm)
-grab the new marker with left-click and try to move to the left or right
-ardour crashes here, creating a core dump
.....
-ardour will not crash if i first create a new location marker and move them on the time line and than create the tempo marker and do the steps above. in this case it is important to 'move' the location marker, if i just create it an do not move, ardour will crash.

this is all happening on ongoing-rev2531 with jackd running no-realtime.

here is the backtrace:

here i believe are some additional lines, which belongs in the front of the backtrace and i missed to copy&paste before:

I found this bug a couple of weeks ago, and I just sent a patch to ardour-dev@lists.ardour.org earlier today that fixes it for me.

I've now uploaded it here too.

all right, i just applied the patch to ongoing@2679 and it is working good, no more crashes when moving tempo/meter marker.

thanks for the patch and cheers,
