ubiquity crashed with InstallStepError in configure_bootloader()

Seems like it had not been disabled if config.dat can be trusted:

$ grep -A4 ubiquity/install_bootloader /var/cache/debconf/config.dat

This isn't the same as bug 260001.

The fact that unchecking the boot loader box doesn't work should be fixed by my fix for bug 348660. However, there's also a bug here that installing the boot loader didn't work. Could you reproduce this with 'ubiquity --debug', and attach /var/log/syslog and /var/log/installer/debug? TIA.

Well, I asked it to not install any boot loader, since I installed to a dmraid which I think grub-installer does not support.

I have already starting using this installation so I can not test by reinstalling from scratch again, no more free partitions on this raid setup. But I can try all the steps up to the real reformatting and installation. Or install to an external drive, but that will not be raid.
