Your post reminded me to check something, though. I use N-Series PC Suite, which came with Nokia Photos version 1.0.x. It also has an auto-updater, which reporded no updates to the components.
So how come Nokia Photos 1.2.x was available for download from the Nokia N-Series website? I've had to update it manually.
I'm hoping this will fix the "out of memory" errors on the device when synchronising a large number of items (requiring the device to be rebooted before it will continue with synchronising), and maybe speed up the incredibly slow synchronising of text messages, but this could be a firmware issue.
