Mate problems

[Frank McCormick <debianlist@videotron.ca>]

I am running Debian Stretch/Sid on AMD64 and noticed for the first time 
a problem with a Mate application. The Mate accounts dialog won't run 
because it detects gtk2 on the system.


(mate-accountsdialog:12108): Gtk-ERROR **: GTK+ 2.x symbols detected. 
Using GTK+ 2.x and GTK+ 3 in the same process is not supported
Trace/breakpoint trap


Does anyone else have this problem ? Is there a way to fix it?

Thanks
