‘qemu-img info replication:’ causes segfault

Typing the literal command ‘qemu-img info replication:’ causes a segfault.  Note that ‘replication:’ is not a filename.

$ ./qemu-img info replication:
qemu-img: block.c:2609: bdrv_open_inherit: Assertion `!!(flags & BDRV_O_PROTOCOL) == !!drv->bdrv_file_open' failed.
Aborted (core dumped)
