A319 flight crew describes a 'hard power transfer' when the number 2 engine is shut down during taxi in. The number 1 engine was unresponsive to power lever movement; although all engine indications appear normal. The number 2 engine is restarted; the number 1 shutdown and the aircraft turned over to maintenance at the gate.

Narrative:
On number 2 engine shut down there was a very hard power transfer. Captain stated that she lost all throttle control of number 1. I immediately hit the yellow pump and started the process of APU start up. Notified ground we might be stopping with an engine issue. (I did not touch number 1 engine!) number 1 engine shows normal running indications captain went full power no thrust; pulled back to idle and full again with no power change then back to idle. AC was not dark APU and number 2 engine were off number 1 engine showed running with no control. We were able to turn off and stop in a pad after APU start and we secured number 1 engine as we didn't know why it was non responsive. Restarted number 2 engine since it shut down properly and called operations to call for maintenance to meet at gate and resumed taxi to gate. I sent a brief message with events to maintenance control since there was no specific error or ECAM to report or trouble shoot. Additionally during morning acceptance walk around after maintenance had the AC all night in inspection; I found a bird strike. Maintenance improperly shut down AC during bird strike inspection which caused some reset issues. This could have been an additional factor for our event later that day. Next day one of the mechanics stated an engine 1 cannon plug disconnected I don't know if this was true.
