Yes !
We (25,000 users, 65 GB of mailboxes, mixed POP3 and IMAP4 spool access with a few shell users thrown in for good measure) are bitten by this a couple of times per week.
The issue has emerged and re-emerged on this list for a number of times.
And what is your Qpopper config ? Do you continue to use server mode even though this could be the reason ?
I did a test of my own, and as I suspected, with server mode enabled, if I log into a pop3 session, then delete a message from the middle of the spool via imap, when the pop3 session terminates the spool is pretty much hosed.
However, with server mode disabled there aren't any problems that I'm aware of.
(Except for the obvious - which is that during a pop3 session, imap wont see the messages, because they're no longer in the spool until the pop3 session is over - but there is no corruption)
