Sorry yes this is indeed a bug in Froyo. :( I have patch to fix this now in the Froyo tree:
https://review.source.android.com/16151 I can't tell you when it will appear on various devices, but hopefully we can get it rolled out fairly quickly. (Note -- do expect to see devices updating to Froyo for a while without this patch, since there is a fairly long natural lag between code going in and builds being created with it and going through TA to be delivered to devices.)
