How can I export Gantt to PNG?
I've installed ImageMagick and RMagick gem, but I can't see any "Export to PNG" button in Gantt page.
Information Screen shows that RMagic is unavailable, but installation of RMagic gem was successfull

Changing rmagick gem version to 4.0.0 solves the problem.
The same problem will never occur in upcoming Redmine 4.1.0 because it does not depend on RMagick any longer. Please see #30492 for details.
