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.
