During a Rosegarden session a qsampler crash caused the following output in
[11530.642970] qsampler: segfault at 00000008 eip b73f52c5 esp
bfe77e20 error 4
snd-usb-caiaq log: snd_usb_caiaq_midi_send(f6d52b40): usb_submit_urb()
[13720.859888] qjackctl.bin: segfault at 00000314 eip b7b07a7f esp
bfbe8f54 error 4
There are segmentation fault errors from qsampler and qjackctl, but perhaps
there's also a problem in caiaq-midi.c .
