Seen on Trixe-backports with 0.91.9~bpo13+1:

$ sudo sbuild-qemu-update /autopkgtest-trixie-amd64.qcow2

The same issue exists on unstable with 0.91.10:

$ sudo sbuild-qemu-update /autopkgtest-forky-amd64.qcow2
/usr/bin/sbuild-qemu-update:236: SyntaxWarning: "\<" is an invalid escape sequence. Such sequences will not work in the future. Did you mean "\\<"? A raw string is also an option.
  "image exists at that location, then $IMAGEDIR\<image> is tried.",
