xen-create-image is part of xen-tools, which is not developed by core
Xen developers. So this one should be reported to xen-tools
maintainer(s).

I remember some xen-tools version has a bug regarding memory size. Are
you using Debian's package version? Could you try the lastest
xen-tools from upstream? Did changing "M" to "Mb" help (it should work
for both Squeeze and Wheezy)?

I wrote a patch some time ago to make the parser handle memory suffix
but was not upstreamed. You're welcome to take that and upstream it,
or implement some cleaner solution.
