** Description changed: + [ Description ] + + When launching Qt applications from indicators under Unity, the theme + isn't right. + + [ 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.
