Thanks Tito!
That seems to have fixed that problem. But I'm still having other
problems :-(

On a different machine I see this problem when I try to bring up the LV2
GUI for the encoder plugin in, say, ardour3:

[xcb] Unknown request in queue while dequeuing
[xcb] Most likely this is a multi-threaded client and XInitThreads has
not been called
[xcb] Aborting, sorry about that.
xcb_io.c: 179: dequeue_pending_request: Assertion
xcb_xlib_inknown_req_in_deq'failed

And then ardour3 crashes.
