Shift-reloading in FF 16.0.2/OS X 10.6.8 any page at the English Wikipedia using the monobook skin consistently gives me the following error:
Error: TypeError: mw.getConfig is not a function
Source File: https://bits.wikimedia.org/en.wikipedia.org/load.php?debug=false&lang=en&modules=startup&only=scripts&skin=monobook&*
Line: 1
The error consistently disappears if I switch on debug mode (&debug=true).
Appears to come from the mwEmbedPlayer loader inside the generated setup() function.
Version: unspecified
Severity: critical
