To replicate, have a exposed filter that returns the same results for 2+ values (I had a node type filter with only one node so all other node types returned empty results) and have the exposed form display with the view (ie. not a block). The views rows will be correct, but the exposed form stay with whatever the first one searched was.
Ie type filter with values image, file, video that all result in empty page. Click image and apply, aok shows 'image' selected. Click 'file' and apply, and it goes back to showing 'image' selected. Click 'video', same thing.
Patch adds build info the the key map in views_plugin_cache's get_output_key function; not sure if this or something else is desired, but looks to be whereis heading to make a unique-ish key. Appears to be working so far.
Views3 looks to have the same issue and patch, other than line numbers, looks to be the same.
