  Thanks.  In your case it looks like something called "whysynth" is 
the issue:

/usr/lib/dssi/whysynth.so

  This is shown in the _dl_map_object() entry in the backtrace:

#10 0x00007ffff7fd59cd in _dl_map_object (loader=0x0,
    loader@entry=0x7ffff7ffe220, name=name@entry=0x7fffdc1a3e30 
"/usr/lib/dssi/whysynth.so", type=type@entry=2, 
trace_mode=trace_mode@entry=0, mode=mode@entry=-1879048191, 
nsid=<optimized out>) at dl-load.c:2336

  Try uninstalling that.  The others might still be an issue, so don't 
be surprised if it continues to crash and more plugins need to be 
uninstalled.

  There appear to be a number of issues with the various DSSI synth 
plugins.  Someone needs to open bug reports against each of these 
crashing plugins and mention all the others.  That should get us closer 
to finding the real problem.

  This bug report against rosegarden can be closed.
