Since this happened during apport-collect 526367 I assume you first:
1) Power off and close Laptop (T61 or x61)
2) Place laptop in docking station
3) Turn on laptop via docking station power button
4) Login and start a session
5) Press the undock button
6) Remove laptop from docking station, laptop will suspend
7) Resume laptop, but it will go back to sleep (not subject of this bug report)
8) Resume laptop second time
9) Laptop built-in display will stay black

There is a similar report at bug 535010, which also involves undocking, so this may be the key.
