Comment 1 for bug 26660

Just for completeness, I can't be 100% sure that it's because I used that HFX
partition format that OS X created partitions that make parted spew this error
message, but I _suppose_ that the error message is what causes the front-end to
go bonk. I'll try to get the install logs in case they are useful later.

It's also interesting to note that when using such an HFSX format, OS X creates
a bootstrap partition of its own with its bootloader in it (because I suppose OF
doesn't grok HFSX).
