Bug#976138: qmidiarp: died unexpectedly in non/new-session-manager(NSM)

[rosea.grammostola]

Upstream has the same bug. I'll report it upstream here: 
https://sourceforge.net/p/qmidiarp/bugs/34/

But I'm not using the app atm, so I'm probably not going to spend time 
on it tbh. Lots of Linuxaudio apps have bugs unfortunately, I report 
them, but if I've to trace down them all, it will be a day job...
