Root teminal in pwn box doesnt work

Just wanted to report been trying to bring up root terminal emulator in pwn box and now it doesnt seem to work. Upper right hand corner gives a notification of

"Starting /usr/bin/x-terminal-emulator "

but the root terminal never comes up

only regular terminal works

found a work around if I start certain programs in a rgular teminal like ptunnel it turns the regular teminal into a root terminal but directly clicking root terminal program icon still doesnt bring it up.
