I get the following error when I move the mouse pointer over an indicatorless checkbutton:

unknown color name ""
while executing
"winfo rgb $w [$w cget -selectcolor]"
(procedure "tk::CheckEnter" line 23)
invoked from within
"tk::CheckEnter .c"
(command bound to event)

The checkbutton manual page indicates that "" is a valid value for the -selectcolor option: "If specified as an empty string then no special color is used for displaying when the widget is selected". But the new checkbutton bindings introduced in Tk 8.5.8 don't account for this.

Tested on OpenSuSE 11.2, x86_64, KDE 4.3.1

    Sorry, this is a dup of 2904492 (due to problems with SF there was quite some time between searching for an existing bug and finally being able to submit this one).
