Proposing as an SRU (help me if I'm doing it wrong):
===== When =====
Has an obviously safe patch.
===== Impact =====
I don't know which program available directly within Ubuntu is written in Ruby-GTK+, but those which do and which are using the Ruby Thread class are broken, and of course developing such a program is broken too.
The fix is available in ruby-gnome2 since version 0.19.2 and was introduced through SVN revisions 3692[1] and 3694[2]. Both are within the attachment "ruby-gnome2-gtk-thread-patch.debdiff" in comment #1.
===== Reproduce the bug =====
Here is another example for reproducing this bug:
require "gtk2"
include Gtk, GLib
# Create widgets
window = Window.new
vbox = VBox.new(false, 2)
button = Button.new("Run Thread")
progress = ProgressBar.new
# Pack widgets
window.add(vbox)
vbox.add(button)
vbox.add(progress)
# Set default window size
window.default_width = 120
window.default_height = 50
window.show_all
# Connect signals
button.signal_connect("clicked") do
Thread.new do puts "Thread started!" progress.pulse
end
end
window.signal_connect("destroy") { main_quit }
# Show all and run
main # start the GTK+ main loop
The test program shows a window with a button and a progress bar. Clicking the button will execute a Ruby Thread object, and the GUI visual elements/the GTK+ main loop will remain freezed.
The example in the bug description is supposed to print dots, and instead it doesn't.
