[Owncloud] OwnCloud Impress.js App Problems

[Jy Yaworski]

I read the OwnCloud documentation on the impress app and copied the 
example to demo.impress. Yet, whenever I try to view it, nothing 
happens. I get the following information in the log:

{"app":"PHP","message":"pathinfo() expects parameter 1 to be string,

Any ideas? This is OwnCloud 5.0.4. I just created the demo.impress file 
from the Files App.
