Yes; that ruins the whole purpose of choosing of the LGPL --
not only does the GPL not allow proprietary software to link
against it (which is, for me, the whole point of licensing a library
under the LGPL), but a change from LGPL to GPL is also oneway.

The only situation I find such a license transformation morally ok is
when taking parts of the code to incorporate in a project (let's say
that a library contains a neat utility function that might be useful in
another project.  Linking against a library just for the sake of a
single utility function is pretty over the top, but borrowing that code
(properly credited, of course) feels perfectly fine.
