It looks like after updating to WordPress 3.5 any galleries opened via albums do not open and appear blank.
Galleries seem to open OK individually (i.e. using separate shorcodes rather than linked from galleries).
Seems others are having similar issues. Have tried 2012 theme and clearing the NextGen cache folder (Options > Images > Clear cache folder) and then clear browsers cache, but it did not resolve it.
Have not tried deactivating all other plugins yet, will do so and post back.
