Sorry I didn't see this and reply to it earlier. This symptom happens
to my Claws every few months. When it does, what I do is collapse and
right click the account in the folder list, then click rebuild folder
tree, which dumps *all* cache from *all* folders in that account. I do
this on the theory that whatever bitrot is causing it in the directory
I noticed might be operating on other directories and might eventually
cause lost data.

My computer information is listed after my sig.

Of course what you and I are doing is just fixing the sympom. The real
answer is to fix whatever is corrupting the headers. But because this
is such a sparse intermittent, it's very hard to fix. If anyone ever
comes upon a way to reproduce this symptom at will, please forward that
reproduction sequence to the developers so they can fix this once and
for all.

Thanks,
