I've figured out that this is caused by the fix to #36051. If override_redirect is set (as in around line 353 in windows.c), the window manager ignores the window, which has the advantage of making it borderless, but in KDE's case, has the disadvantage of making it unfocusable. I have no idea why it only behaves this way on amd64. I'm going to look into making it borderless by setting the window type to NET_WM_WINDOW_TYPE_DOCK, which is how xmms does it, but meanwhile it should probably be left as-is - an Eterm that won't go borderless is probably better than one that won't take focus.
