kdesu, kdesudo doesn't work for KDE apps without QT_X11_NO_MITSHM=1

http://imgur.com/k0akqHC

This happens for kate, kwrite, systemsettings... any KDE apps I try to run with kdesu or kdesudo just come up as empty windows. If I use kdesu or kdesudo (or sudo) to start something non-KDE, like libreoffice or gimp, will launch fine. I'm in KDE, by the way.

Here's the output from kdesudo or sudo (this repeats over and over)

X Error: BadShmSeg (invalid shared segment parameter) 128
  Extension:    130 (MIT-SHM)
  Minor opcode: 2 (X_ShmDetach)
  Resource id:  0x5400016

EDIT: Title has been edited, formerly "kdesu, kdesudo don't work for KDE apps, result in empty windows"

Re: kdesu, kdesudo doesn't work for KDE apps without QT_X11_NO_MITSHM=1

I see. I just found this page, which says:

QT_X11_NO_MITSHM – stops Qt form using the MIT-SHM X11 extension.

So for some reason, MIT-SHM isn't working as intended.
