The tight squeeze between the RJ terminal and A was an accident waiting to happen once A380s began taxiing on A.
Perhaps signs at the appropriate distance declaring
Get your tail past here before contacting apron
would help.
If I was Airbus Industrie, I'd make up the signs and have the local tech crews plant them.
If you want to get fancy, have flashing lights illuminate the obstruction when it interrupts the beams so the A380 crews would know the way was blocked.
