I have been working on a bug in Gallery2 for longer than I care to say. The problem is that in the dynamic keyword album in Gallery2, it will match more keywords than it should.
For example if you visit the "man" keyword album you will also get the "woman" keyword album in the results, as well as anything else that has the word "man" in it.
Another example, which is taken from a real-life situation, the dynamic keyword album "Wind" was also matching the keyword "Wind generation".
