Skinned OS X Spark application still named "Spark"

The OS X builds of our custom skinned Spark are failing to pick up the Application Name input. I have it set to “WMC Talk”, yet:

  • The disk image has a volume name of “Spark_2_0_7” when mounted.

  • The application is named “Spark”.

  • Because of this, the Application Menu (the one next to the Apple menu) reads “Spark”.

I’'d prefer this to be fixed rather than adding more steps to our workflow for client distribution.
