Don't crash if gnome-shell is not running/installed (7.56 KB, patch)

Description Adam Dingle 2013-03-27 10:18:45 UTC 
I'm attempting to run gnome-tweak-tool 3.7.4 on Ubuntu 13.04 (Raring).  It crashes on startup:

gi._glib.GError: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface `org.gnome.Shell' on object at path /org/gnome/Shell

I'm running Ubuntu Unity, not GNOME Shell.

gnome-tweak-tool is very useful, and it would certainly be nice if it would run even in environments where GNOME Shell is not present.

(See also the corresponding Ubuntu bug at https://bugs.launchpad.net/ubuntu-gnome/+bug/1159124 .)

Can you test this patch against master?
Comment 3 Adam Dingle 2013-03-27 11:48:03 UTC 
Thanks for the quick fix.  I just tried the patch (on Ubuntu 13.04 with Unity) and it runs!  I do see this on the console:

===
WARNING : Shell not installed or running
WARNING : Shell not running
None
WARNING : Error detecting shell
Traceback (most recent call last):

+ Trace 231690

  • File "/usr/lib/python2.7/dist-packages/gtweak/tweaks/tweak_shell_extensions.py", line 199 in __init__ 
    raise Exception("Shell not running or DBus service not available")
Exception: Shell not running or DBus service not available 
INFO    : GSettings missing key org.gnome.nautilus.desktop (key computer-icon-visible)
===

Regarding that last line (about org.gnome.nautilus.desktop), I'm running Nautilus 3.7.90.  Perhaps the warning wouldn't occur with a different Nautilus version.

In the tweak tool itself, the Shell section includes the options "Show date in clock" and "Whether the clock shows seconds", which have no effect in Unity.  It might be nice to hide those options when GNOME Shell isn't running.  But that's a small point; as it stands this patch is a great improvement over the current situation (i.e. not running at all).
