G10 CCD defects?

I have just been told that there are some G10s capturing image with a horizontal line near the upper left corner of every picture. The detailed symptom is described here

It's said if the 5th number of the serial no. is 0 or 5, the camera could be affected.

I checked my camera with serial no. of 6928003529, and the problem is there. Potential buyers please be careful...
