Attempted to install a plug-in again. I'm going to be integrating with source control and defect tracking soon, so I would like this addressed.
Thanks

Finally found a solution referencing another bug: adding
-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar

to eclipse.ini seems to have solved problem.
