Bug#398161: Crash when partition is created with blank label

[James Utter]

Package: debian-installer
Version: Etch beta 3

Platform: powerpc

When creating partitions, if I remove the default partition label ('untitled', i think) so that it is blank, the debian installer freezes.
Repeatable: Yes
Severity: Crasher

I am installing debian testing etch beta 3 on an iMac (powerpc).
