[pkg-cinnamon] Bug#763565: [cinnamon] News from upstream author

[VOR (Micha vor dem Berge)]

Just got confirmation from an upstream author (see last mail, github
link) that this is a known bug in cinnamon 2.2:

"You're still on Cinnamon 2.2 it looks like - this particular freeze has
been fixed in 2.4. [...] Unfortunately, the fixes are not things we can
backport (we completely updated cjs to a newer upstream, and refactored
Cinnamon as well)"

What I didn't mention before: This bug freezes my complete desktop,
partly it can not even be recovered by doing a 'killall -HUP cinnamon'.
This is why I will set Severity: Grave.

Best regards,
Micha
