Package: vlc-plugin-qt Version: 3.0.8-0+deb10u1 Severity: grave Dear Maintainer,
I have all my Qt 5 applications rendering their UI via GTK2 (this means I have qt5-style-plugins package installed): > QT_QPA_PLATFORMTHEME=gtk2 > QT_STYLE_OVERRIDE=gtk2 Additionally, for my GTK3 applications, I have client-side decorations disabled (with gtk3-nocsd and libgtk3-nocsd0 packages installed): > GTK_CSD=0 > LD_PRELOAD=libgtk3-nocsd.so.0 The above should have nothing to do with GTK2 UI rendering, still it affects vlc (actuallly, vlc-plugin-qt) in Debian Buster/Devuan Beowulf (everything worked fine in Debian Stretch/Devuan ASCII). Also, I have to mention that cvlc (without Qt UI) works fine. Now, to the problem. Whenever vlc is laucnhed in the above environment: > $ QT_QPA_PLATFORMTHEME=gtk2 QT_STYLE_OVERRIDE=gtk2 GTK_CSD=0 > LD_PRELOAD=libgtk3-nocsd.so.0 vlc -- it prints the following and just hangs, w/o even showing a window: > VLC media player 3.0.8 Vetinari (revision 3.0.8-0-gf350b6b5a7) > > (vlc:25026): GLib-GObject-WARNING **: 23:35:25.110: cannot register > existing type 'GtkBuildable' > > (vlc:25026): GLib-GObject-CRITICAL **: 23:35:25.110: > g_type_interface_add_prerequisite: assertion 'G_TYPE_IS_INTERFACE > (interface_type)' failed > > (vlc:25026): GLib-CRITICAL **: 23:35:25.110: g_once_init_leave: > assertion 'result != 0' failed > > (vlc:25026): GLib-GObject-WARNING **: 23:35:25.111: cannot register > existing type 'GtkWidget' > > (vlc:25026): GLib-GObject-WARNING **: 23:35:25.111: cannot add class > private field to invalid type '<invalid>' > > (vlc:25026): GLib-GObject-WARNING **: 23:35:25.111: cannot add private > field to invalid (non-instantiatable) type '<invalid>' I can also provide the output of `vlc -vvv` here, but it wouldn't be indicative, as, the above errors are purely GTK-specific. *If* I change either GTK_CSD to 1 or LD_PRELOAD to an empty string (or Qt UI style to anything different from gtk2), then vlc starts just fine and shows its window, controls, etc. All other (even complex) Qt 5 applications (assistant, designer, wireshark, KDE appplications etc.) are not affected by either GTK_CSD or LD_PRELOAD. The problem is reproducible using a new clean user profile with default vlc settings. The problem has also been reported to Devuan as bug #432 <https://bugs.devuan.org/db/43/432.html>.
