Installer crashed with OSError: [Errno 17] File exists when taking a photo for login screen.

[fdondon]

The system was already partitioned (Ubuntu 11.04 was installed before, and update to Oneiric failed).
I didn't choose to format the file system containing / as I want to keep as much data as I can.
As said in title, the crash occurred while taking the photo with embedded webcam.

System : Dell Vostro 1510.

Looks like bug 495217, fixed in ubiquity 2.9.19 in precise.
