Artists appear twice in my library

I've noticed a bug in the library on my profile (first noticed a couple of days ago, thought it had cleared until this morning, when it is much worse), where several artists are listed twice when viewing by play count. It is fine if I switch to ABC ordering. The affected artists usually get fixed if I scrobble a track of theirs. The other day it was just two artists, now it is several.

I presume this is just a bug and not something I have done?

This often happens in my library too. Here are some of the duplicated artists followed by the pages they appear on today.

Nolwenn Leroy 25 26
Deniece Williams 25 26
L'Âme Immortelle 41 42
Meiko 45 46
Sara Paxton 48 49
Chungking 50 51
Annie Barker 52 53
B*Witched 51 53

This issue is also in another recent thread: http://www.last.fm/forum/21713/_/617719

My guess (untested and unproven) is that this happens when the artists spanning pages have the same playcount. For example, if the last two artists on p5 have 100 plays, and the first two artists on p6 have 100 plays. When loading p6, it says "give me two artists who have 100 plays", and on some occasions this will include the same artist which it grabbed for the end of p5 too.

I'll do some more formal testing of this in a while :)

The neighbours list seems to behave similarly, sometimes. I've found the user listed at the bottom of one page listed again on the top of the next.

wow, the definition of 'shortly'. ...btw, the A-Z bug is back too.
