Version:            (using Devel)
Installed from:    Compiled sources
Compiler:          gcc (GCC) 4.2.3 (Ubuntu 4.2.3-2ubuntu7) 
OS:                Linux

Steps to reproduce:

1. Open Konqueror, make sure that "Open as tab in existing Konqueror when URL is called externally" is enabled in "Settings->Configure Konqueror.../General".
2. Go to another desktop and open KMail.
3. Click on a http:// link in a message.
4. Konqueror crashes bacause of a failed assertion, backtrace below.

Expected behaviour:

Open link in a new tab if there is a Konqueror instance running on the same desktop (this actually happens), but leave Konqueror sessions on other desktops unchanged.

This happens no matter if I run the applications on a KDE3 or KDE4 SVN desktop. I'm running KDE and qt-copy from SVN trunk rev. 825430, compiled on Kubuntu 8.04.

The backtrace looks like it's related to D-Bus. My D-Bus version is 1.1.20-1ubuntu2. I'm not sure if the problem is in Konqueror itself, but I don't know the internals well enough to decide this.
