> ctrl Z => marker is restored in the xml editor but not on the drawing

Reproduced on Windows XP, Inkscape trunk revision 12812.

> Now it will start behaving strangely
> The undo menu always "set markers" no matter how many ctrl-Z you do...
> You won't be able to set another marker...

After undoing the "Remove node" action, I can set a new marker from the Fill and stroke dialog. Undoing again then redraw the first marker.
