Public bug reported:
I loop-mounted a backup image (created with dd) of an xfs filesystem, and did
some copying, deleting. It all went well for some time, then suddenly mc
reported some error and the image file has been umounted or something. I was
unable to mount it again. Mount returned with a wrong fs type/bad superblock
error, even if I specified xfs. Somewhere around this time I noticed the crash
sign and reported it. I had two such files, one of them I managed to handle
flawlessly, but with this second one I was unlucky.
The files were ~10GB in size.
They were located on a software raid volume.
