[ardour-dev] Region context menu problem

Thu Oct 12 12:40:26 PDT 2006

Running ardour2 out of svn, revision 983.

Create a new session, add a mono track. Record a half minute or so of
silence. Back up the playhead, record more silence (to create two
overlapping regions).

Right-click on one of the regions. Choose "lower to bottom layer". The
first time, the region disappears. Select the other region and do the same
thing. This time ...

Segmentation fault (core dumped)

Backtrace follows:

Program received signal SIGSEGV, Segmentation fault.
