Version:           1.2.2 (using KDE KDE 3.2.3)
Installed from:    Mandrake RPMs
OS:                Linux

Reproducible: always

Steps to reproduce:

1. Draw any line (e.g. an association)
2. Double-click in its middle to create a node, dividing it into 2 segments.
3. Select Edit->Undo

Actual result:
The action which is undone, is drawing the line.
Clicking "Redo" brings the line back, but without the node and with all attributes lost (e.g. cardinality).

Expected result
Only creating the node on the line should be undone. No other attributes of the line should be affected.
