Comment 6 for bug 1470700

I can't really test this as is. The problem is that, to test it, I need the new thumbnailer from silo 10, but the ppa includes the old thumbnailer. I can't easily get the new thumbnailer onto the device because Jenkins builds for Wily, not Vivid.

Not sure what I can do for the moment. To test that networkAccessible() thing really is fixed, put the device into flight mode, and it should return zero. If the device isn't in flight mode, it should report that the network is accessible (even before sending the first request).
