Public bug reported:
When gnome-terminal is _not_ running, execute the command
gnome-terminal --preferences
Select the Profiles tab, and click on Edit to edit whichever profile.
gnome-terminal crashes.
The main idea behind "gnome-terminal --preferences" is that if someone
screws up their gnome-terminal configuration big time (e.g. set a custom
command that fails), they can fix it. This crash makes it impossible
using this convenient approach.
The crash is not present in upstream gnome-terminal, it is caused by the
transparency patch. 0001-Restore-transparency.patch adds this snippet to
src/profile-editor.c:
gtk_widget_style_get (GTK_WIDGET (
terminal_window_get_active (TERMINAL_WINDOW (transient_parent))),
"background-darkness", &style_darkness,
NULL);
transient_parent is NULL in this case, and terminal_window_get_active()
is not prepared for that.
Crash is present in Artful (3.24.2-0ubuntu4) as well as current Bionic
(3.26.2-3ubuntu1). Xenial is not affected because the cmdline option
--preferences didn't exist back then.
