This message is awfully long.  What about splitting it while we're there:

                   warn_report("a program lacking bitmap support "
                               "modified this file, so all bitmaps are now "
                               "considered inconsistent");
                   error_printf("Some clusters may be "leaked, "
                                "run 'qemu-img check -r' on the image "
                                "file to fix.");

Not a native speaker, but here goes anyway: "compatible with".

The nits I picked predate your patch, so:
