patch manager needs improvement

[Peter Baumann]

1) patch mgr shows only the 10 most recent patches, but doesn't state that clearly. should provide a brief text and maybe an option to see all patches.
2) download of patches leads to the error below:

While doing a GET operation on /patchmanager, Trac issued an internal error.

(please provide additional details here)

Request parameters:

{'patchop': u'Download'}
