After a patch has been applied, the planner/resolver appears to require the metadata for the old version of the patched bundle before new software can be installed even though that old version will not be part of the solution.

Steps:
1) Start with Eclipse 3.6.1
2) Using the repo attached to bug 332164 (https://bugs.eclipse.org/bugs/attachment.cgi?id=184811) install "RCP Patch V2" (uncheck group items by category)

3) Restart -> Install new Software.  
4) Uncheck "Contact all update sites during install to find required software".
5) Install Eclipse EGit from http://download.eclipse.org/egit/updates-nightly

-> Operation cannot be completed : 
Cannot complete the install because one or more required items could not be found.
  Software currently installed: Eclipse SDK 3.6.1.M20100909-0800 (org.eclipse.sdk.ide 3.6.1.M20100909-0800)
  Missing requirement: toolingorg.eclipse.equinox.launcher 1.1.0.v20100507 requires 'bundle org.eclipse.equinox.launcher [1.1.0.v20100507]' but it could not be found
  Cannot satisfy dependency:
    From: Eclipse Product Configuration 1.0.0.M20100909-0800 (org.eclipse.rcp.configuration.feature.group 1.0.0.M20100909-0800)
    To: toolingorg.eclipse.equinox.launcher [1.1.0.v20100507]
  Cannot satisfy dependency:
    From: Eclipse SDK 3.6.1.M20100909-0800 (org.eclipse.sdk.ide 3.6.1.M20100909-0800)
    To: org.eclipse.rcp.configuration.feature.group [1.0.0.M20100909-0800]

6) Press Back, Select Contact all update sites, then next.  A solution is now found.  

The found solution does not actually require org.eclipse.equinox.launcher_1.1.0.v20100507 because of the previously installed patch, however the metadata for v20100507 needed to be present for the solution to be found.
