I have written some code to display a basic GUI window, which shows a
dialog box for preferences (an action in the code) which is crashing the
program with this Error displayed in cmd:
#C:/Ruby187/lib/ruby/gems/1.8/gems/qtruby4-2.1.0-x86-#mswin32/lib/Qt/qtruby4.rb:2874:
[BUG] Segmentation fault
#ruby 1.8.7 (2011-12-28 patchlevel 357) [i386-mingw32]
Here is the main code and I have kept the other scripts as attachments.
I am running Ruby 1.8.7 on Windows 7.
