typing the name of an installed program into the dash text box fails to bring up the program launcher, typing the full file name of the program results in a empty dash that is unresponsive. Uninstalling and reinstalling the applications did not help. So far the programs I have found that elicit this behavior are file-roller (Archive Manager) and gconf-editor (Configuration Editor). Neither the executable file name or the application title will produce a launcher, the launchers also cannot be found by searching through 'More Apps' -> 'Installed' -> 'see xx more results' which led me to believe that the desktop files are missing, however they are present in the /usr/share/applications/ directory. The programs can be launched from the command line or through the 'run' dialog(<alt><f2>).

This also occurs for the evince (Document Viewer) application. Evince does not appear in the list of installed applications, and cannot be found during a search, but the application is installed.
