Well, since libstdc++.so.6.0.14-gdb.py is a Python script, it certainly is NOT an ELF file, so the error message is correct. Now since the file is not a part of Ubuntu, what third party package did you install to get it? On my system, Sage installs a copy, but I did install the Sage files in their own directory, not the system directory, and have never had a problem.
