I've seen these symptoms too, and have been attributing them to the pile 
of extensions I use to make Thunderbird livable.

Thunderbird generally seems to be less than reliable at maintaining 
local storage and metadata. It doesn't take much to corrupt an index 
file. While there's no loss of email data, read-state and flags (tags) 
can get wiped.

These index problems can be avoided if you use IMAP for storage, it 
seems. I've been wondering of the folder view metadata also would 
benefit from this.
