Could you show the output of:

gdb /usr/local/libexec/dovecot/pop3 # or whatever path it is in
x 0x3829233d20
x 0x3829233ce0

I guess the client isn't being destroyed properly for some reason..

These are simply broken subscription entries that have never worked.
They're not supposed to begin with a ".". In older Dovecot versions they
were shown to clients, but I don't know what clients would have done
with such broken entries. I guess some could have shown them
"correctly", some could have shown them in a broken way and some could
have just ignored them.
