Sorry, I did not try to reinstall Pidgin (thinking that it might really be a corrupt image). I don't actively use it and was only testing it previously, I was more concerned about the "behind-my-back" repos that I had to disable. After disabling "dev-extras" (and "diablo-sdk", I believe), I was successful in uninstalling the "corrupt" version of Pidgin and am simply leaving it there for now.
