Fritzing fails to export stripboards correctly

Steps I took that resulted in the problem:

I used the Radio Shack stripboard, then File > Export > as Image > svg

What I expected should have happened instead:

The vertical lines are too thin, much thinner than the pinhole diameter. Also, inside the pinholes, some solid stuffs occur.

My version of Fritzing and my operating system:

Fritzing 0.9.3.b
Linux Mint 17.3
