 Hi
 Been using imagemagick/convert for years.  I have been running automated
 tests.

 After upgrading to version ImageMagick 6.9.9-40 i get an error when
 running the image magick convert command.
 Abort trap: 6

 on converting an image that had previously worked using older versions.

 I note that this is not the most recent version of imagmagic, also i don't
 appear to be able to downgrade to an earlier version using ports.

 the same command works fine on ubuntu using Version: ImageMagick 6.9.7-4
