Since FileError is on the oilpan heap, this should be
RefPtrWillBePersistent<FileError>.

Thank you for the fix!

It seems that what I should have done is to look at FileError.h and follow the
class's inheritance chain until it reaches 
RefCountedWillBeGarbageCollectedFinalized, then look up the table at
http://www.chromium.org/blink/blink-gc.
Though it'd be even nicer if this could be caught by the compiler with something
like static assertions.

+    OwnPtr<EntriesCallback> m_entriesCallback;
+    OwnPtr<ErrorCallback> m_errorCallback;
 };
