I see this problem too. Thunderbird 2.0 beta 2, Linux. No IMAP here. I don't know if it's related but the error console shows :

Error: [Exception... "Component returned failure code: 0x80550008 [nsIMsgDBHdr.markHasAttachments]" nsresult: "0x80550008 (<unknown>)" location: "JS frame :: chrome://messenger/content/msgHdrViewOverlay.js :: anonymous :: line 452" data: no]
