I found the problem. I don't know the correct long-term solution.

The problem is caused by the patch pushed in GIT hash 2b178a53, 2011-10-26 (SVN revision 1260900). The patch was pushed to resolve bug report 394.

I rebuilt tdebase with that patch reversed. Now I have no problems whatsoever using kate as normal user and concurrently as root through tdesu. The patches from bug report 692 have no ill effects either as I now have both my normal user kate and root's kate configured to use Calvin's patch for MDI usage. When I first start kate as root and then concurrently run kate from konsole as normal user, I no longer see the weird dcop warnings.

Thus far I do not notice any xsession "Klauncher could not be reached via dcop" errors as originally reported in the bug report.

Reversing the patch restores the code to 3.5.10 status. I run both KDE3 and TDE and in KDE3 I notice none of these problems. With the reversed patch, behavior is now the same in both desktops.

Yet as I mentioned, I don't know whether the patch is correct. If the patch is required, then the change has nasty effects and needs resolution elsewhere.
