just plugged in a new external drive and wanted, as i do each time i get a new external backup drive, to reformat it ext4. but now sudo gparted brings this:

[kcrash] TDECrash: Application 'gpartedbin-gtk-tqt-application' crashing...

this is similar to a problem i encountered recently with my scanner software. i'm running ubuntu 16.04 with TDE 14.0.5.

anybody know how i can fix this?
