No problem. That's why bug reports can be merged :)

Hehe my fault that I didn't make my last sentence which you didn't quote
not clear enough.
We currently only read the sector of the 0.90 superblock in and check
that.

The message would be "Unsupported RAID version: %d.%d"
But now that I see the code, it's possible that it doestn't get at all
displayed even if 1.0 stores the superblock at the same posisition as
0.90. Which I think they do.
I look into this now, if I can get it to at least display the error in
that case and maybe even with all 1.x formats.

Thanks for the report :)
