RaynerApe -- thanks for pointing the bug out.
i've really no clue what is causing it -- the queries you are pointing at are valid and far from resource hogging. Moreover, the second one is the same as the one used in 1.2.
i suspect it might come from tabs and carriage return formats, so i gave removing those a try. you might want to try downloading beta-5 and report your findings by email (denis _|at|_ semiologic _|dot|_ com), here, or in the plugin's comments. i'd be curious to try to pinpoint what is causing it.
else, i suggest you try asking Paula for a past version. I no longer have it, but considering she missed my announcement of v.2 beta after unsubscribing from the comments, she might.
