Qjackctl 0.4.2 segfaults immediately after startup on my
(fully updated) Archlinux system (qt 5.7.0, fluxbox).
0.4.1 works OK.

Anyone else seen this ?

Backtrace:

A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
