Bug#694406: Backported patch

[D. Michael McIntyre]

I've attached a patch for your convenience.  I expect this patch will probably 
apply cleanly and work just fine against whatever version of Rosegarden is in 
your repository.  It's very limited in scope and impact, and is very unlikely 
to carry hidden consequences.  It appears to fix the upstream bug 100%.
