Bug: Internal connections on parts with sub-parts cause crashes

Steps I took that resulted in the problem:

Create a fully assigned part with two or more sub-parts with two or more pins each.
Add an internal connection between any of the pins
Save the part
Drag the part onto the schematic view
Drag a second basic part onto the view (e.g. a resistor).
Attempt to connect another part to one of the pins

What I expected should have happened instead:

The connection should have succeeded

My version of Fritzing and my operating system:

Windows 10 Version 0.9.3 (b5c895d327c44a3114e5fcc9d8260daf0cbb5280)

Please also attach any files that help explaining this problem
Here is a simple hack of the SSM2220 part that exhbits the problem:
SSM2220 - Audio Dual Matched PNP Transistor.fzpz (6.2 KB)
Just add it to a project and then try to to move any of the sub-parts or connect any of the pins.
