Vanilla Pd 0.44.0 and Pd 0.44.0-extended-20130213 crash when the audio interface is set to a Fireface UCX (possibly any external interface) and in the Sampling rate is changed on the device. This is confirmed under OS X 10.8.
Steps to reproduce:
1. open Pd, set audio interface to Fireface UCX
2. change sample rate in Fireface USB settings
3. Pd shows this error and then quits:

("uplevel" body line 1)
invoked from within
"uplevel #0 $docmds"
when using -stderr the console shows:
