There is a known issue with QtWebEngine crashing when compiled with GCC 6. The 
crashes can be solved by compiling QtWebEngine with 
-fno-delete-null-pointer-checks (you may want to check with your distribution 
about this).

The Akonadi Server crashes are more concerning to me, would be nice to get a 
backtrace of that (you can attach "gdb" to a running process (gdb -p `pidof 
akonadiserver`) and get a backtrace once it crashes.
