** Description changed:
Regression from gutsy to hardy.
I have a tivial dot file:
---------------------------------------------
digraph name {
rankdir = LR ;
node [shape = circle]; s00
node [shape = circle]; s01
node [shape = circle]; s02
node [shape = doublecircle]; s03_one
node [shape = doublecircle]; s06_two
node [shape = doublecircle]; s09_three
s00 -> s01 [label = "a"];
s00 -> s01 [label = "b"];
s00 -> s01 [label = "c"];
s00 -> s01 [label = "d"];
s00 -> s01 [label = "e"];
s01 -> s02 [label = "f"];
s01 -> s02 [label = "g"];
s01 -> s02 [label = "h"];
s01 -> s02 [label = "i"];
s01 -> s02 [label = "j"];
s02 -> s03_one [label = "a"];
s02 -> s06_two [label = "b"];
s02 -> s09_three [label = "c"];
}
---------------------------------------------
The dotty shipped with gutsy displays this file without a problem. Dotty
on hardy hangs and never renders.
+
+ Impact on users: dot files can trigger a bug that causes dotty to hang.
+ The bug has been fixed in upstream 2.16.1, and is fixed in all versions in
Ubuntu from Intrepid onwards
+ A minimal patch from 2.16.1 was provided previously, as was a debdiff. The
debdiff has been reformatted to address a previous complaint.
+
+ The bug can be reproduced using the simple dot file described above.
+
+ The only potential for regression is if the patch introduced some new
+ bug from 2.16.1 in the code being patched (but the patch is fairly
+ minimal)
