Hello,
i have here some compressed code from my would-be-application that doesn't
work and i don't know why.
How it should work:
I click the "Open Window"-Button -> a new window opens
I click the "Test"-Button -> a warning-window should open but doesn't
If i remove line 10(TkVariable initialization) everything works well.
What's wrong with initialization of the TkVariable at this point?
Hope someone could help me and thanks in advance

Heres the code:
=== snip
#!/usr/bin/env ruby
require 'tk'
class MyWindow < TkToplevel
def initialize
super
@value = TkVariable.new
this_button = TkButton.new(self) {
text 'Test'
pack('side' => 'left')
}
this_button.command { TkWarning.new("Can you read this?") }
end
end
root = TkRoot.new
root_button = TkButton.new(root) {
text 'Open Window'
pack('side' => 'left')
}
root_button.command { MyWindow.new }
Tk.mainloop
=== snap
And that's the backtrace:
