Gallery not longer working after upgrade to OC 9.1 when application files_move is enabled

[TDannhauer]

Bug report

Steps to reproduce

1. Install OC 9.0.4
2. Upgrae to 9.1
3. Activate files_move app <-- Important, since this is the showstopper
4. Log into OC
5. Activate Gallery app.

Expected behaviour

Gallery should show up, load the thumbnails and display them.
Clicking on the "file view" icon in the upper right corner switches back to file view.

Actual behaviour

Browser Title changes to Gallery.
No photos are shown. T
In the upper right corner the icon for switching back to file view appears, but is dead (No function on clicking on it.)
Switching back to file view is only possible via the main app selector in the upper left corner.

Firebug reveals an error in the console:

In OCA.Files.fileActions.register() it throws "TypeError: OCA.Files.fileActions is undefined"

That app is unmaintained and pollutes all apps by loading its scripts everywhere.
I have provided a patch there:
