Have anyone encounter this bug?
When you lock your phone (or the phone lock automatically), it will show the Enter lock code screen:


I just found out today that if you press anywhere outside the Enter lock code screen (the area marked with red block), it will pass the phone lock and show "Device not locked" message:

And now you will be able to access the phone

Is phone lock useless on Maemo? Am I the only one to suffer this problem?

@freemagon,
I am sorry in advance if this bug not related to CSSU thumb.
I post it in here because I am using CSSU thumb on my N900.
I don't know where else to post this.
