How is this game a draw?

From what I see, the computer didn't declare a draw but instead aborted the game (which in part means no ratings are changed, unlike which is possible with a draw).
I've had a number of aborts. Typically my impression is that the computer is convinced there is a win possible, but it's really a dead draw and the 50 move rule will soon have to apply. That clearly doesn't explain your case though.

The computers decided to draw this game for no apparent reason, white was obviously winning. Am I missing something?
