Version:           0.7 (using 3.5.9, Kubuntu (hardy) 4:3.5.9-0ubuntu7.1)
Compiler:          Target: x86_64-linux-gnu
OS:                Linux (x86_64) release 2.6.24-19-generic

Program looks like working well, but when I close it, and save changes, the start menu is the same! Nothing is changed! And on terminal I read this:

badboy@badboy-laptop:~$ sudo kmenuedit
Error: "/var/tmp/kdecache-badboy" is owned by uid 1000 instead of uid 0.
QImage::smoothScale: Image is a null image
ERROR: Communication problem with kmenuedit, it probably crashed.
badboy@badboy-laptop:~$ X Error: BadWindow (invalid Window parameter) 3
  Major opcode:  20
  Minor opcode:  0
  Resource id:  0x420208d

From when I get it, to now, It never worked. I use the KDE 4.1 version of Kubuntu 8.04 64 bit.
I hope to be for you helpfull!
Good Evening, Leo
