regression: mscgen v0.15+ cannot create the "2nd sample graph"

[GoogleCodeExporter]

What steps will reproduce the problem?
Attempt to create a graph of the second sample listed on the website (as png).

What is the expected output? What do you see instead?
A graph - I get "mscgen: main.c:340: arrowR: Assertion `0' failed."

I have not traced the reason for this, so all I can say for now is that the
function "arrowR" gets a wrong type as argument.

What version of the product are you using? On what operating system?
Debian/Linux, using mscgen 0.15 and trunk revision 31.

Please provide any additional information below, including sample input
file:

# Example MSC using boxes

msc {

   # The entities
   A, B, C;

   # The relations
   |||;
   # Next three on same line due to ','
   A box A [label="box"],
   B rbox B [label="rbox"],
   C abox C [label="abox"],
   |||;
   A abox B [label="abox"];
   |||;
   B rbox C [label="rbox"];
   |||;
}

NB: The first sample is generated without issues (only checked png version
though).
