The following .dot aborts with rankdir set to LR, but it does not abort if rankdir is not set.

Aborted

The "input causing the bug" is generated with [user@machine graph]# php workflow_diagram.php --group_by_workflow=no

Without rankdir=LR; in the second line of the "input causing the bug" dot does not abort (But draws the graph up down in stead of left right...)
