It's possible you get the following error message with Pashua:

Or textual:
-[__NSCFString count]: unrecognized selector sent to instance 0x7f91e05237d0
This is probably due to misspelling option on a popup-control (or combobox/radiobutton), so you should fix your Pashua-configuration (workaround).
However, Pashua should provide a proper error message for this.
