Comment 73 for bug 1251281

"So my conclusion is that the fix in the trusty-proposed repository as it stands there right now is not helpful at all, but the version in ppa:rtandy/flashback repository works fine."

Not helpful? Without fix in trusty-proposed gnome-session will not start session... Segfault in libgnome-desktop is another bug/problem and is not directly related to this bug. And probably should be reported as separate/new bug.
