Comment 4 for bug 1180880

This turns out to be a ubiquity bug after all. The .bgf font format used by bterm is architecture-dependent - for example, it depends on the architecture's pointer size - but we were putting unifont.bgf in an architecture-independent package so it was always the i386 version. The fix is just a matter of making ubiquity-frontend-debconf be Architecture: any rather than all. I'm test-building that now, and it should be a straightforward SRU candidate.
