[DRE-maint] Bug#737200: ruby-rmagick: 2 examples for the documentation fail (only) on i386 during build

[Cédric Boutillier]

Package: ruby-rmagick
Version: 2.13.2-2
Severity: normal

The problem reported in http://bugs.debian.org/733723
is still present. On i386, two examples run to build the doc by the
post-setub.rb script, namely doc/ex/shadow.rb and
doc/ex/stroke_linecap.rb fail with an error looking like:

> /usr/bin/ruby1.9.1 -I /«PKGBUILDDIR»/./lib -I /«PKGBUILDDIR»/./ext/RMagick stroke_linecap.rb (example 156 of 188)
> /«PKGBUILDDIR»/lib/RMagick.rb:1836: warning: assigned but unused variable - current
> stroke_linecap.rb:42:in `draw': pixels are not authentic `' @ error/cache.c/QueueAuthenticPixelCacheNexus/4387 (Magick::ImageMagickError)
>                        from stroke_linecap.rb:42:in `<main>'

Those result in three missing image examples in ruby-rmagick-doc when
built on i386 (shadow_before.gif, shadow_after.gif, stroke_linecap.gif).
However, running those examples directly from the command line do not
generate any errors and the corresponding images are created.

It is a mysterious bug, probably in imagemagick itself.
