Subject: qt4-ruby crash

Hi,

i had one of the worst idea in my life one month ago: port a working
ruby-gtk2 app to ruby-qt4. Not only it becomes a non-sense to use ruby
since your code looks like to a c++ app written in another language (you
almost lose all advantages of a clean ruby port like ruby-gnome2,
exception messages are unclear when it's qt related) but it crashes in a
way that is incredible:

/usr/lib/ruby/site_ruby/1.8/Qt/qtruby4.rb:2680: [BUG] object allocation
during garbage collection phase
ruby 1.8.7 (2010-08-16 patchlevel 302) [x86_64-linux]

The first time i had this message, i surrounded a piece of code with
calls to GC.disable and GC.enable to make the damn thing work.

And now i fall in the same problem in another part of code but this
time, GC.enable/disable doesn't work.

It's related to qt::treewidget: it works if sorting is not enabled but
it crashes if it's enabled.

Does anyone have any idea about this problem?

Thanks.

Linux 2.6.35.6-48.fc14.x86_64, qt 4.7.1, kde 4.5.3
