Pushed by mart into branch 'master'. append views as the first thing it may still be a crash on screen added with the corona locked M +1 -1 shell/shellcorona.cpp http://commits.kde.org/plasma-workspace/04f4eaa51559b6af092351f6939143cf1ea7d71a
a proper fix needs modifications in plasma-framework, that is already released, that means, 5.1 it needs to temporarly unlock the corona when a containment is added for reasons like a screen has been added
*** Bug 337345 has been marked as a duplicate of this bug. ***
Do we need the check for immutability in Corona::createContainment ? removing the " if (d->immutability == Types::Mutable) " seems massively simpler than temporarily unlocking and locking again.
