 0.4.1 works OK.
 Anyone else seen this ?
 
 first note that qjackctl v0.4.3 is the most recent release.
 are you, by any chance, using the Setup / Misc / "Start minimized to
 system tray" option as from a previous v0.4.1 configuration ? also note
 that this troubled option vanished on 0.4.2. however, due to many kind
 requests, returned on 0.4.3 and is indeed guilty of the ill behavior
 similar to the one you report. 
Never used that option, and in 0.4.1 it's greyed out (apparently
since I don't enable the system tray icon).
  as last resort, what happens when start on a blank
configuration? hint:
 remove or backup the ~/.config/rncbc.org/QjackCtl.conf file away, making
 sure you can restore it back later, then launch qjackctl again. 
With the config file removed 0.4.2 works. It segfaults again
when restarted with the 'Single application instance' option
disabled.
