It seems to be some problem with current codepage of Thunderbird. Only
in my case it also failed to open in application. And it creates magic
27 byte files..

thx for the link.

of course, @ bug,  "won't fix". sigh.

here, my cache _were_ all turned off, and offline was off, too.

in the end, per your comments, I've settled on

   browser.cache.memory.capacity"   40000000
   browser.cache.memory.enable"   true
   browser.cache.memory.max_entry_size   40000000
   mail.imap.mime_parts_on_demand"   false
   mail.server.default.mime_parts_on_demand   false

easily deployed to user.js to prevent this for others.

thx!
