How about:

apt-get source -b mumudvb

That does it all in one command.

Raspbian is armhf, it is just armhf for armv6 rather than armv7 that
the official Debian armhf uses. All raspbian packages will work on an
armv7 debian system, but not the other way around (as you found out).

No, but maybe the problem is in one of the libraries and not the package
itself. I think your gdb backtrace actually pointed to a library so
maybe that is the package you have to recompile.

Worst case would be that the package contains explicit armv7 assembly
code, which would be annoying. Not that likely though.
