I have been running the Debian version with the patch for the past few weeks.  Here is my experience...

I have three machines set up to access the same IMAP account, all using dIMAP.  Often I will move mail to trash, delete mail, etc. on machine A, then refresh my view on machines B and C some time later.  When refreshing B, I routinely get several dialogs stating "messages so-and-so were deleted in folder such-and-such, do you want to delete them locally?" followed by a list of message UIDs.  I typically get one dialog per folder that has changed.  I also have a separate spam folder, in which old messages are automatically purged every once in awhile; I get dialogs for this folder too whenever some messages have been purged.

The dialogs are slightly annoying and seem to me to be not strictly necessary (aren't we worried about the *client* telling the *server* to delete mail incorrectly, based on a corrupt index?), but they are a small price to pay on the path to fixing this bug.  So far I have not had any mail loss, even with a few situations in which a flaky wireless connection has died in the middle of a refresh.  (Previously, such situations were a high risk for mail loss in my experience.)

This evidence is anecdotal, as I've never found a reliable means of inducing mail loss.  However, I think it is encouraging that my mail has survived through a couple of scenarios that may have caused loss in prior versions.
