[Tails-dev] Jessie session localization (#7897)

Hi,

I'm giving up on https://labs.riseup.net/code/issues/7897: Fix
localization of GNOME session. We have a working workaround but I can't
find a proper fix after hours of research and tests.

Would someone please have a look? Should we ask GNOME developers?
Consider the fix good enough?

Thanks by advance,

Cheers
