tidy.gui() font button throws error

[Dasonk]

I'm running Ubuntu 12.04 currently. If I use tidy.gui and then click on the font button at any point this is what I get:

> tidy.gui()
> Error in widget$getGroup : $ operator not defined for this S4 class

It creates a new window with a frame named "Size" but doesn't populate that window with anything. It's not a big concern for me but I thought you might want to know.

Here's my sessionInfo

Should be fixed now. Thanks! There has been some changes in gWidgets for gtext() which I did not notice.
