Great:

removing from cache before deletion - no effect, the problem persists;
removing from cache after deletion - the mail is deleted from IMAP server, problem disappears;

Indeed, setting (setq gnus-use-cache 'passive) the problem no longer persists, as of course the items don't enter the 
cache.

So, at least temporarily as a fix, before it's debugged, this means redefining the `E' key in gnus group summary mode 
to first issue the operation associated with E and then remove the item from the cache. I can do this, but with intense 
effort, so if you can propose easily the .emacs code for this temp solution now, it'd be great.

In the meantime, I'm ready to work on debugging it, so that the workaround isn't necessary.
