CLI installer or Setup Wizard? Have you tried both?

@keithbentrup Thank you for reporting, can you please give us more details, what version and if you are using sample-data. Also, did you have a previous installation? Please clear your var directory if you did. If you are using sample-data, can you please ensure you using the master branch.

@xcomSteveJohnson Nope have'nt seen this before, but there were some changes related to Observers recently

[keithbentrup]

not using the sample data; var is empty
pretty clear why this is failing .. the referenced file doesn't exist.

seems like it's the sort of issue that should be caught by automated testing
