I have the same issue. I have this armor loaded on Pellagina. Within a second or two of loading the inventory screen for her the UI locks up, though some parts of the game are still responsive, e.g. I can alt-f4 to exit the game. I've also experienced this locked up on the normal exploration view on a map including a drake, though I was able to reload an older save where she was in the party where this did not happen (though it did lock up once I brought up the inventory screen). This appears to have started with the 2.1 patch.
