Bug#856072: mate-volume-control-applet crashes on mouseover

[Julian]

Package: mate-media
Version: 1.16.0-1
Severity: normal
File: /usr/bin/mate-volume-control-applet

Hi,

the mate-volume-control-applet crashes at least once a day (but randomly) when
the mouse cursor is put above the applet symbol or it is clicked. I have then
to restart the applet manually.

Console output says:

(mate-volume-control-applet:11484): Gtk-WARNING **: Calling
gtk_widget_realize() on a widget that isn't inside a toplevel window is not
going to work very well. Widgets must be inside a toplevel container before
realizing them.

(mate-volume-control-applet:11484): GLib-GObject-CRITICAL **: g_object_ref:
assertion 'G_IS_OBJECT (object)' failed

(mate-volume-control-applet:11484): Gdk-CRITICAL **:
gdk_window_get_scale_factor: assertion 'GDK_IS_WINDOW (window)' failed

Gtk:ERROR:/build/gtk+3.0-LMY5Pb/gtk+3.0-3.22.7/./gtk/gtkwidget.c:5808:gtk_widget_get_frame_clock:

There are no syslog entries.
