No. This bug has already been fixed through the use of mesa, and it's a bug in whatever commandline nvidia installer you're using if files belonging to packages are being mangled. The Ubuntu packages already include a mature and tested system for ensuring the correct libGL is used on the system, even though more than one might be installed, and mesa is already *not* on the linker's path when supported nvidia packages are installed.
In any case, this is the wrong bug report on which to be having this discussion. This bug report is about a crash present in 12.04, in which QtWebkit was not linked against libGL *at all*. The bug report covering the libGL conflict is bug #1155327.
