This bug appeared during an upgrade from Maverick to Natty. Running the nspluginwrapper command through gdb implicates the Google Talk plugin. Removing the google-talkplugin package allows nspluginwrapper to install correctly. The Natty updater should probably uninstall google- talkplugin (please reassign to the appropriate package if update- manager-core doesn't cover that).
