Bugzilla Bug 99886

After running "mksquashfs /src dest.squash -info -keep-as-directory" I found
that it both segfaulted and /src did exist. The utility should handle this case
properly and not segfault. Possibly relating to this, I found the resulting
dest.squash was completely corrupted with directory names of jibberish.

Reproducible: Always
Steps to Reproduce:
1. mksquashfs /exists dest.squash -info -keep-as-directory
2. mksquashfs /dosnt-exist dest.squash -info -keep-as-directory
3. mount -t squashfs -o loop dest.squash /mnt/floppy

Actual Results:  
step #2 segfaults and the contents of the squashfs image is corrupted

Expected Results:  
error message is printed by mksquashfs and the contents of the image are that of
/exists

I just added squashfs-tools 2.2 into portage.  Can you see if this resolves
your
problem, please?

Will do when it gets into the portage mirrors.

Tested, it does not segfault but still produces a squashfs image when the src
does not exist.

This should be fixed in 2.2_p2 ebuild... Thanks to the author for being so
quick
and making a new version for me... ;]

Tested, works perfectly.
