Thanks for the hint but unfortunately every qemu command quits with
a segfault with this image:

scotty images # qemu-nbd nweb.img
Segmentation fault

[192749.840652] qemu-nbd[16052]: segfault at 7f88b1382000 ip
0000000000419492 sp 00007fff1e94f710 error 7 in qemu-nbd[400000+31000]

It's sad that a segfault of Qemu/KVM can corrupt a whole image
while the host itself was running without any problems as the
segfault happened. Seems that the data is lost. But thanks again
anyway!
