Bug occurred while attempting to reinstall TeamViewer, after it disappeared from my system. I have asked an Ask Ubuntu question here https://askubuntu.com/questions/957745/libdbus-shared-object-library-causing-teamviewer-issues with some details on the troubleshooting process I was going through when this error occurred, though there were many more stages to the initial debugging process. My current hypothesis is that perhaps the 64 bit and 32 bit versions of the libdbus shared library have become incorrectly cross-linked in some way and this is blocking correctly installing or removing the library.
