Hi folks. I think we've got this now, in git master :-)
I rewrote how we delete things when closing the gui.
I believe it's correct now.
Tests OK with AMSynth, Calf, Synthv1.
Bonus: Since we use GtkPlug for our plugin gui container window,
I found out it is better than using GtkWindow. (I tried it.)
For example using GtkWindow, AMSynth fails to embed into the
container window resulting in /two/ separate windows on screen.
While with our GtkPlug it opens fine all the time :-)
Still, I added two #defines in there:
LV2_GUI_USE_GTKPLUG (enabled by default)
and
LV2_GUI_USE_QWIDGET (disabled by default)
The latter define tells MusE to use QWidget instead of
QMainWindow for a plugin gui container.
I found there was no difference so I left it at what
we have always used, the QMainWindow.
Yay. Try 'er out guys!
Lemme know how it goes.
Tim.

Ever since I updated to |debian stretch|, |kernel 4.9.0-3-rt-amd64| and
recompiled muse, muse crashes 49 out of 50 times when I close a LV2
plugin (native gui). See the transcript below for what muse writes when
I start muse, open a LV2 native GUI and close the LV2 GUI.
It doesn't matter if I close it via its window close button or by
clicking on its name in the effect rack. And it also happens with the
GUIs of the LV2 "synths".
Starting with a clean slate by clearing my .config/MusE folder and
starting with one of the provided templates still produces the crash.
Compiling MusE with the "|supplied|" lv2 support failes with two errors
like:
|/usr/src/sound.d/muse/muse3/muse/lv2Support/lilv-0.22.0/src/world.c:584:1:

‘lilv_world_load_bundle’ was here |
I then tried to downgrade liblilv from 0.24.2-dfg0-1(stable) to
0.20.2-dfg0-1 (oldstable), but I still couldn't compile.
* As a side-note: how can I make muse save my window layout? It tends
to start with a ridiculously narrow track-list and an impractical
zoom, even after I resized things and saved the song.

LV2PluginWrapper_Window::~LV2PluginWrapper_Window() The program 'muse3'
received an X Window System error. This probably reflects a bug in the
program. The error was 'BadWindow (invalid Window parameter)'. (Details:
serial 593 error_code 3 request_code 10 minor_code 0) (Note to
programmers: normally, X errors are reported asynchronously; that is,
you will receive the error a while after causing it. To debug your
program, run it with the --sync command line option to change this
behavior. You can then get a meaningful backtrace from your debugger if
you break on the gdk_x_error() function.) /home/martin/bin/myMuse: line
