Actually, I've upgraded jQuery core to 1.9.1 because that was the one known to be compatible with jQuery Mobile 1.4.5.
For the file upload, I've upgraded to the released a bit after jQuery Core 1.9.1.

Indeed, we can try upgrading the file upload to a yet newer release but first, I need to be able to reproduce the issue.
