Comment 3 for bug 278408

I can confirm this on a fresh install of Kubuntu Jaunty. Only I don't even get the blank window - it just hangs immediately after I press the "New" button. I have to kill it using "kill -9" to get it to exit. Running from the command line gives:

gfm@chief% sudo kppp
Error: "/var/tmp/kdecache-gfm" is owned by uid 1001 instead of uid 0.
Error: "/tmp/kde-gfm" is owned by uid 1001 instead of uid 0.
kppp(10441) KToolInvocation::klauncher: klauncher not running... launching kdeinit
Error: "/tmp/kde-gfm" is owned by uid 1001 instead of uid 0.
Killed
gfm@chief%

The first two "Error" lines appear immediately on starting kppp. The last two lines "kppp(10441) and "Error" appear when I press "New". Again, I have to kill using "kill -9".
