in thread Gtk2 apps are seg-faulting my Tk apps

unfortunately I no more see your links to bugreports you've pointed earlier.

Last time I saw conflict with perl/Tk is a symbol with same name within .so library; but your current error is probably much more complicated than that, so I hardly can be of help here...
I hope you'll finaly figure out how to avoid the problem
