FF74.0 in UBudgie 19.10 : LIBDBUSMENU-GTK-CRITICAL dbusmenu_menuitem_property_set_shortcut: assertion 'gtk_accelerator_valid(key, modifier)' failed

[Coeur Noir]

Hi,

on a freshly installed Ubuntu Budgie 19.10, I've noticed Firefox is kind of slow at start :
⋅ I can launch Firefox but it’s unresponsive for a moment ( no blinking cursor anywhere )
⋅ then cursor eventually appears in address bar but blinking slowly and not usable,
⋅ still, clicking anywhere has no effect, or effect delayed much later,
⋅ a moment later, cursor blinks at its usual pace and Firefox becomes responsive as expected.
The whole process takes 30 seconds to 1 minute and Firefox runs rather ok later on with some slow moments though ( sometimes tabs are slow to react, or any interactions with buttons in FF menu ).

Same behavior in safe-mode ( without any FF addons )

Same without any Budgie applets regarding app-menu ( such as pixel-saver or global-menu applets ).
