[Bug 414027] Re: dotty hangs with cpu spin for "apt-cache dotty monodevelop" graph

[Martin Olsson]

Here is the output of "apt-cache dotty firefox" from ubuntu 12.04:
http://temp.minimum.se/apt_cache_dotty_firefox.txt

I tried "dotty apt_cache_dotty_firefox.txt" just now and it took 100%
CPU for 5mins but no graph so I CTRL-C'ed it.

Title:
  dotty hangs with cpu spin for "apt-cache dotty monodevelop" graph

Status in “graphviz” package in Ubuntu:
  Confirmed

Bug description:
  This works just fine on Ubuntu karmic:
  apt-cache dotty binutils | dotty -

  These ones gets stuck inside a CPU spin and never finishes though:
  apt-cache dotty gedit | dotty -
  apt-cache dotty firefox | dotty -
  apt-cache dotty monodevelop | dotty -

  The first part (e.g. "apt-cache dotty firefox") finishes just fine so
  the bug must be in dotty or later on in the chain.
