Summary0001314: Dot fails to process graph with rankdir=LR and landscape=true

If a graph (a digraph in my example) has both rankdir=LR and
landscape=true attributes set, the graph will draw downwards (as if the
graph has been rotated 90 degrees) and the output will either be very
dirty (not correct) or completely blank. If the same DOT source is passed
to dotty or OmniGraffle, the graph draws correctly. This has been
confirmed on Mac OS X 10.5 and recent Ubuntu and FreeBSD builds of
graphviz. This can be worked around by removing the landscape attribute.
Steps To Reproduce

// Produces blank (or corrupt) "downward" graph
digraph "testgraph" {
graph [ rankdir=LR, landscape=true ];
A -> B

// Produces correct graph as expected
digraph "testgraph" {
graph [ rankdir=LR ];
A -> B
Additional Information

[elllson] The output of: "dot -Tpng" looks correct to me?
\<A HREF="b1347.png"\>(attached)\</A\>

The output of dotty looks like it is ignoring landscape=true since it is not rotated on the screen.
Not a big deal, since landscape mode is not particularly useful on a screen. Its mostly intended for printing.

What output format are you using?
