Upon starting showq qjackctl prints in its Messages window: 14:06:17.923 JACK connection graph change. 14:06:18.115 JACK connection change. and its Connections pane shows the first two outputs of ShowQ being connected to system:playback_1 and _2. Here the GUI dialog box "Show Q encountered an unknown-error. Please report this error to the developers of the program" is displayed. Upon pressing "Ok" ShowQ exits and jackd reports subgraph starting at ShowQ timed out (subgraph_wait_fd=28, status = 0, state = Triggered, pollret = 0 revents = 0x0) > > It is best if /you/ try running a debug session under KDevelop, > > or use gdb stand-alone.

All it prints is (gdb) run Starting program: /usr/bin/showq [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
