In 0.94 and 0.95 beta the Marker example (hide.fo) throws the following
Exception.

I have attached a sample file which more closely matches the use case that I
discovered this issue from. This works fine in 0.25 but is broken in
0.94/0.95beta.
The stack trace from running this example on 0.94 is slightly more useful than
the one from the example:
