[Bug 514899] [NEW] Multithreaded Gtk applications using Ruby bindings freeze

[dismal_denizen]

Public bug reported:

Binary package hint: libgtk2-ruby

In Ubuntu 9.10 with the version of libgtk2-ruby from the repositories
(0.19.0), new threads cause the Gtk main loop to freeze. As an example,
the following code will never produce any output:

 require 'gtk2'

 Thread.new do
   sleep 1 # Look busy
   exit    # Finished, exit
 end

 # Main loop
 loop do
   # Process all currently pending events
   Gtk.main_iteration while Gtk.events_pending?
   print '.'
 end

However, when the latest version of the bindings is installed (0.19.3)
the program works as expected, filling the screen with dots.
