Yes, nm-applet is now using GTK3. Unfortunately the reason it is 
crashing is because we preload our kgtk library (LD_PRELOAD environment 
variable). This kgtk library is based upon gtk2. any time those symbols 
or code mixes, it will crash.

A workaround is to remove the variable and then launch it.

Submit a bug report for gtk2 problems only, and the conflicts i 
mentioned above. A GTK3 engine is on the wishlist but is unlikely to 
happen anytime soon.
