Version:           Qt: 3.0.5  KDE: 3.0.4  Konsole: 1.1.3 (using KDE KDE 3.0.4)
Installed from:    Compiled From Sources
Compiler:          Configured with: ../gcc-3.2/configure --with-stabs --enable-threads --with-cpu=i686   Thread model: posix    gcc version 3.2 
OS:          Linux

This applies to kde 3/1beta1 as well.

I will be happy to help track down this problem if you can give me some idea of where to start.

I have a MSI G4MX400 video card that uses a Nvidia g-force4 MX440 chip set and has 64 Megs of RAM as well as an output for a second monitor.

I have configured Xwindows 4.2 using the Nvidia drivers downloaded from their web site. Nividia calls the xinerama mode "twinview". Note: if I turn off twinview, I can start several instances of konsole.

All KDE 3.0.4 has been compiled with xinerama support and QT 3.0.5 has been compiled with threading support.

I am able to start several instances of all kde apps except konsole. After starting one instance of konsole, an attempt to start a second instance causes it to load and the window flashes quickly on the desktop before dying. I tried starting a second instance from the command line in the hope that it would display some messages but nothing.

A look at .xsession-errors shows the following:
kio_pop3: POP3Protocol::~POP3Protocol()
kdeinit: PID 361 terminated.
DCOP: register 'konsole-364' -> number of clients is now 10
DCOP: unregister 'konsole-364'

A log of the final startup of X shows: (note there are no errors and X would log any if there were even if they occur later on)
