After posting this I'll (try to) reboot back into the installation (SL 5.2) and hope it still works...
Edit: Saved bugreport as plain text, compressed and attached, as well as a few snapshots.
Reported as bug 1515
Solution: download the attached patch (SL53patch.txt), open a terminal, login as root or su to root, then enter
Code: Select all
patch /usr/lib/python2.6/site-packages/pyanaconda/storage/devices.py < /path/to/SL53patch.txt
Thén launch the installer and make sure you leave "install grub to" as it is, the MBR.
Running liveinst-update-quick in a terminal did not work for me.
