Under the Hurd, when device file is passed as an argument to "parted",

The reason is using store_typed_open instead of store_open.  More
information can be found in $HURD/libstore/store.h (or
/include/hurd/store.h).  Basicly, store_typed_open expects something
like "device:hd0", while store_open expects something like "/dev/hd0".
Needless to say, the latter is what everyone would try.  The first style
is equivalent of (MAJOR,MINOR) pair in *nix, and the second style is
equivalent of block device file name.

It seems that the bug is in libstore, not in parted.  When
store_typed_open doesn't find ":" character, it calls store_open.
Unfortunately, it does it incorrectly, and, as a result, store_open is
not called as intended.  There is second bug somewhere in
store_find_class, called by store_typed_open.  Some dlsym magic is used
to find store class.  I'm investigating what exactly goes wrong
(resulting in SIGSEGV) when the store class is not found.  A patch will
follow if I find out.

I'm reassigning this bug to the hurd package.
