I had an issue with this on a wordpress site and a change I made reduced it by nearly 100%. I am not sure you are experiencing the same problems or not but have a read - [webmasterworld.com...] I go into a bit more detail in the 4th post and posted the unexpected GWT related results in the 10th.
Mod's note: URL for copying into browser, as WebmasterWorld redirect script breaks the hash character in the above link...
[edit reason] added url [/edit]
