Description Jaak Ristioja 2008-03-18 08:47:45 UTC
I was on a ~x86 host connected to a amd64 VNC host with a bigger resolution with a different aspect ratio than mine, full colors, fullscreen, resizing the display, when the SIGABRT occured. Here's the backtrace of krdc crashing on the ~x86 host as reported by the KDE crash handler:

Comment 2 Timo Gurr (RETIRED) gentoo-dev 2009-05-27 09:56:02 UTC
Probably nothing we can do about. Please retest with krdc of 3.5.10 and file an upstream bugreport if it still happens in the KDE4 version of krdc. Since upstream doesn't care about KDE 3.5 anymore chances are low that it'll get fixed for the KDE 3.5 version.
