Certainly a shame something like this happens so close after opening.
Based on the information given, aka this is the departure side of the terminal, all we know is the blue cabin wasn't moving. Whether it didn't attach to the haul rope (lift auto stops in that case), power failure, or slippage, quite a few possibilities in regards to why the cabin was stopped.
Lot of theories out there right now in regards to the actual collision. Someone from liftblog.com has a good theory though:
That’s usually what’s happens when the lift operators acknowledge and start again after an automatic stop from the anti-collision system… without any investigation and looking if all gondolas are still moving!
In this case, they probably re-started the lift at least two times to get such stacking and a high speed collision which break the gondola glass!
The broken glass could be just a bad angle and not from speed, but who knows. But very likely human error as lifts have many systems just to make sure something like this doesn't happen. But you never know, multi failures can happen.

We even joked about the cars looking like they would collide coming into the station, because they do come in quickly and stop suddenly.
Needless to say, with a product this new, this is terrible press and this is going to hurt Doppelmayr more than it’s going to hurt Disney.
It is standard procedure for the lift manufacture to be on site a week or two after opening to continue to monitor the lift to make sure everything is functioning properly. Someone has a picture out there with Doppelmayr trucks in the parking lot backing this up. Doppelmayr North American headquarters are over in Salt Lake and they certainly don't have trucks just sitting in a state they just built their first installs in.
With the tight cabin spacing, there is little room for error. I'm sure Disney will spread out spacing by removing cabins for a while.
Doppelmayr has no name anywhere, I'm doubting many people know who made it, most will think Disney made the system. The D-Line is proven technology (this coming from a Leitner-Poma fan) that has many installs in Europe and is slowly starting to be introduced here in the states. The only thing that is different at Disney is the accessible cabins being broken off every so often, but as mentioned, this accident happened when the cabin was supposed to be accelerating out, not where cabins merge back in.
