While the 5.1.0 does not solve the main issues (Unity 8 crashes), there's difference to 5.1.1 regarding this bug: qtubuntu compiled also for x86 against Qt 5.1.0:
https://launchpad.net/~ubuntu-sdk-team/+archive/testing/+packages?field.name_filter=&field.status_filter=published&field.series_filter=saucy
So something changed between upstream 5.1.0 and 5.1.1 versions that may need to be workarounded in qtubuntu.
