gnome-shell flooding journal on each alt-tab

[rustylynch]

Each time the user alt-tab's between windows on a Clear instance running the default gnome desktop, the following dump is made into the journal:
gnome-shell[838]: Object Shell.GenericContainer (0x3f19f40), has been already finalized. Impossible to get any property from it.

Every thing appears to be functioning correctly, and is just an annoyance when trying to mine the log for actually useful info.

Note that this issue has been around for a while. It just finally bugged me enough to report it.

A quick search yields potential culprits from upstream gnome shell that has yet to be closed:

We have applied Marco Trevisan's patch [1] which avoids the noise at the logs. This patch should be reverted once the change is applied upstream and it soon will be available in a Clear Linux release.
