Bug#303608: libqt0-ruby1.8: incorrect include in qtruby library badly polutes Module namespace

Package: libqt0-ruby1.8
Version: 4:3.3.2-1
Severity: important

A mistake in the use of include means that Qt methods were being added
to "Module" badly poluting its namespace.  This bug also breaks the
rubyscript2exe program.

The good news is that this problem has been fixed upstream but since
it is a pretty serious problem I am hoping that the fix gets into

Here is a discussion regarding the bug from:

Richard Dale replied:

Yes, my mistake was to think of 'include Qt' being just like a 'using
namespace' statement in a static language like C++. But it isn't like
that at all, and in this case was having quite major unexpected

I'd known there was something 'not quite right' in the namespace
handling of QtRuby for a while, but couldn't work out what it was. That
was I was so pleased when you found the problem.
