In an effort to try and pin down the cause of the occasional segfaults that are happening for folks with Bodhi 4.0.0 I have put older EFL versions that were always stable under Bodhi 3.x in the Bodhi 4 testing branch for users to try.
After adding the b4testing branch to your repos - perform your system updates and then run the commands:
sudo apt-get install elementary evas-generic-loaders emotion-generic-players mv ~/.elementary ~/elementaryold
And then restart Moksha.
Note that this roll back will cause some instability issues with the latest ephoto version we have - but everything else seems fine at a glance here on my personal systems. In fact - a couple of the bugs epad has under the latest EFL version aren't there any more and the few theme issues we still haven't sorted with the latest EFL version gone in this roll back as well.
