gitk crashing on Windows.

   Hi.

   When you run gitk from a git repository on Windows it starts up and 
starts updating its 'Row X/Y' output labels. This lasts for a few 
seconds but if you terminate the application before this updating is 
complete you get a Windows message stating:

   'Wish Application has encountered a problem and needs to close. We 
are sorry for the inconvenience.'

   and the standard 'Send Error Report'/'Don't Send' buttons.

   Hope this helps.

   Best regards,
