Steps to reproduce:
1) Build WebKit from source.
2) Run MiniBrowser in Xcode.

These messages are in the console:

I'd guess it's trying to start the correct MiniBrowser but with the system (i.e., wrong) WebKit?

Does the run-minibrowser script work?

No.

[Chris Dumez]

Would help to have a sysdiagnose to investigate. My bet is that we've broken Minibrowser launching when using the Open Source SDK somehow?

I think someone from Sony reported the same thing a few days ago.
