Bug#1138683: dump: Restore -i fails to restore from dumps made by Deb12 dump

[Patrik Schindler]

Hello Alex,

sorry for taking so long.

I could verify that 0.4b54-1 doesn't show the issue, which is an acceptable fix 
for me.

Are you interested in nailing this down for 0.4b49-2 further or shall we leave 
it at this?

:wq! PoC
