[ Fix ] It's because GNOME_DESKTOP_SESSION_ID is unset due to problems in upstart scripts. Qt uses this to decide whether to apply the GTK theme. Fix is to set this as early as possible, in Upstart's xsession- init job. [ Regression potential ] We're setting the environment variable ~all the time in the session. Maybe something could be expecting it not to be set? [ QA ] This is a bit racy, so you might not see it all the time. Install vlc, restart your session (or the sound indicator), then click the indicator and launch vlc. You might see the wrong theme before and should always see the right theme after. [ Original description ] Bug discovered when launching VLC from the sound indicator applet: the QT UI theme is wrong. The theme is correct when launched from Unity launcher or terminal. Please see the attached screenshots. I've tracked it down to a difference in environment in the VLC process: When launched from indicator-sound, the variable GNOME_DESKTOP_SESSION_ID is unset, and this causes VLC to become themed incorrectly. (If the variable is given any value, then VLC looks correct.) To reproduce, either: 1) Launch VLC from indicator-sound (make sure it's not already running and has been started from somewhere else) 2) Or just start VLC like this from terminal: $ GNOME_DESKTOP_SESSION_ID= vlc Looks like a bug in qt4, which seems to depend on GNOME_DESKTOP_SESSION_ID being set [to anything] to pick up the correct theme. (The variable is deprecated, according to its default value in Ubuntu 14.04.) Try: $ GNOME_DESKTOP_SESSION_ID= qtconfig Observe theme not picked up from "Desktop settings" in qtconfig.
