Ubuntu 19.04: Severe GObject/GType error and crash

[moma]

Hello,
I am trying to make Audio-recorder to compile and run under Ubuntu 19.04 (Ubuntu Disco Dingo - development branch).

1) A GStreamer bug.

This crash occurs if I run a Gstreamer pipleline on the command line (in a terminal window). Like this.

$ gst-launch-1.0 -e pulsesrc | fakesink

(gst-launch-1.0:8410): GLib-GObject-WARNING **: 21:31:05.365: ../../../gobject/gtype.c:4265: type id '0' is invalid

(gst-launch-1.0:8410): GLib-GObject-WARNING **: 21:31:05.365: can't peek value table for type '<invalid>' which is not currently referenced
Caught SIGSEGV
Spinning. Please run 'gdb gst-launch-1.0 8410' to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core.
------

2) Also, it seems that the same bug causes my audio-recorder program crash.
It happens in all gtk_button_set_image(...) calls during runtime.

gtk_button_set_image(GTK_BUTTON(g_win.recorder_button), GTK_WIDGET(image));

The error message is:

(audio-recorder:32368): GLib-GObject-WARNING **: 19:21:52.600: ../../../gobject/gtype.c:4265: type id '0' is invalid

(audio-recorder:32368): GLib-GObject-WARNING **: 19:21:52.600: can't peek value table for type '<invalid>' which is not currently referenced
Segmentation fault (core dumped)
----

Please educate me if you want more debug info or stacktrace.

My system is:
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu Disco Dingo (development branch)
Release: 19.04
Codename: disco

My system has very latest updates.

Any comments?

Thanks, that looks like a bug in the current 1.15 tarball which is fixed in git and is going to be fixed with the next update
