DBUS_STARTER_ADDRESS and DBUS_STARTER_BUS_TYPE aren't always unset from environment making gedit and possibly others fail to start

[Stéphane Graber]

SRU note:

[Impact]

Anyone using unity-2d and also using gedit, which can affect a number of machines for which there are no 3d drivers, eg underpowered netbooks.

[Fix]
See lp:~jm-leddy/ubuntu/oneiric/unity-2d/unsetenvvariables

[Test Case]

1) Switch to unity-2d on login
2) Start up Gedit
3) observe gedit does not start

[Regression Potential]
Small, we've been running this patch in precise without issue. Additionally, it's just a 3 line change to unset an env variable.

[Original report]

ISO testing showed that sometimes, only on Unity 2D (so far), DBUS_STARTER_ADDRESS and DBUS_STARTER_BUS_TYPE aren't unset from the environment when starting a new software.

This breaks gedit as it's actually checking these variables for its own DBUS activation

This may well be related to the symptoms seen in https://bugs.launchpad.net/ubuntu/+source/gedit/+bug/827414 (was closed as invalid).

[Alberto Mardegan (mardy)]

An easy way to reproduce it is to kill unity-2d-launcher: it will get automatically restarted, and then the DBUS_* variable will be set.

Hi James,

I have tested this PPA, and tried to open the Gedit for many times, this bug has been fixed. Thanks.

The proposed branch needs fixing, see comments on the merge proposal.
Unsubscribing ubuntu-sponsors.
Please request a review from ubuntu-branches in the merge-proposal & re-subscribe ubuntu-sponsors team for a new review.

[James M. Leddy (jm-leddy)]

Thanks for the heads up. I accidentally cherry picked from the devel branch, which caused the issue. The resubmission should be good.

[Dimitri John Ledkov (xnox)]

unsubscribing sponsors, as the branch is updated/submitted for sponsorship.
