Oh yes -- that crashes the sequencer. Nasty.
There may be a core dump from the sequencer binary
("rosegardensequencer", separate from the rosegarden binary), from
which you can get a stack trace.
Otherwise, you can also run the sequencer process separately, before
the GUI, and run it in a debugger. (Of course this only works if you
have a debugger and enough CPU/memory to run the sequencer happily
from it.)
In this case, we can go to one terminal window and say
$ gdb ./sequencer/.libs/lt-rosegardensequencer
GNU gdb 5.3.92
[startup messages...]
(gdb) run
Starting program: /home/cannam/rosegarden/head/sequencer/.libs/
lt-rosegardensequencer
[sequencer startup messages...]
rosegarden (sequencer): RosegardenSequencer - started OK
Then in another terminal, run rosegarden itself (no debugger) and do
what you were describing. Then when it stops playing, switch back to
the gdb terminal and we see this:
Program received signal SIGBUS, Bus error.

and this at least gives plenty of information to send us a bug report,
if not to start tracking the bug yourself.
