Actually this problem resembles me to another one, it's similar to why gdb
is not working when grafting is used. I believe that the correct solution
to these types of issues would be to recompute the hashes, and provide the
updated hashes to the packages relying on them, so that they know the
correct hash of the grafted file. In the gdb case this seems to be easier
to solve, as the problem occurs inside a single package.
