Description David M. Karr CLA 2011-06-13 18:10:32 EDT 
Build Identifier: 20110218-0911

I'm finding that I may have to revert to an older plugin configuration because of a plugin that unfortunately doesn't work with the latest Subversive plugin. I figured it would be handy to use the "Compare" button in the "Installation History" tab to see what differences there are. I'm going to have to revert to a date almost 3 months ago, so I really need to see the details of what I've installed after that time.

Unfortunately, when I select two configuration entries and then click the "Compare" button, it seems to work hard for a few seconds and then gives me a dialog with title "Compare..." with just the X in the red circle and an OK button. No other information. There is nothing in the .log file related to this. I know there are differences, because I manually searched back until I found the Subversive version that I need to set to. Comparing that with any newer configuration gives me the same result, that uninformative dialog.

Reproducible: Always

Screenshot that shows the empty Compare results.

This shows the result of clicking the "Compare" button after selecting two of the entries in the list.  It chugged for a full minute before presenting the empty dialog.
