I'm very sorry. It's a bug which should be fixed.
But it is not a primary problem for your trouble.
If tile extension is installed (or Tcl/Tk is 8.5 or later), 
Ruby/Tk doesn't use the bugged routine.

Probably, your ruby's tcltklib.so is linked with Tcl/Tk8.4.
Please check the result of 'ruby -r tk -e "p Tk::TK_PATCHLEVEL"'.
If it shows 8.4.x, your tcltklib.so uses libraries of Tcl/Tk8.4.

To fix it, please install tile extension for your Tcl/Tk8.4, 
or re-compile your ruby's tcltklib.so with Tcl/Tk8.5.
I'm not familiar with Ubuntu. So, I don't know which is better.
If igonore it, I recommend you to re-compile tcltklib.so, 
because Tcl/Tk8.5 is better than Tcl/Tk8.4.
