On linux machine everything works fine

timfjord commented 10 years ago

After rollback gem version to 2.13.1 and imagemagick to 6.6.7-0 everything works fine.

mtyaka commented 10 years ago

This issue is caused by a bug in ImageMagick. It looks like it will get fixed in 6.8.8-2: http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=24751

mtyaka commented 10 years ago

I can confirm the problem was fixed in ImageMagick 6.8.8-2.

timfjord commented 10 years ago

Checked with ImageMagick 6.8.8-9 and rmagick-2.13.2. Everything works fine
