To try and pinpoint the problem, I cloned my installation to a fresh partition and renamed .kodi.
I then set the LE config to manually update from the Milhouse LE9 repo. and updated to #427.
I created 2 test profiles, added some media and tried logging on/switching profiles.
With all profiles using Estuary, this works fine.
I then installed Confluence and the common cache addon.
Profile test1 uses Confluence, Master and test2 use Estuary.

Switching to test1 crashed Kodi.

Hope this helps to identify the problem.
I will keep my main installation on #421 and test newer builds in the test installation.

I should add that this is all on a tweaked NOOBS setup, with several Kodi installations, each with their own 16GB partition on a 128GB SSD.
I will make one change to the test installation, as I noticed in the crashlog that it had become the 'master browser', which I do not want.

Thanks, yes - looks to be Python related. @peak3d any ideas?   

 There is may also infinite lock condition, it locks kodi and no more response(actually freeze) and no playback video on youtube addon.
Console still works. only way back control is restart kodi.
