Aye, bug identified is bug half fixed. There was a real bug when we were
using "/" as a folder separator in local maildirs that wrongly caused
trailing slashes. This has been fixed by this commit which I have put
into both the next and master branches of my repository.

Let me know if this is really fixed now, when you use that. This would
justify releasing a bug fix release pretty soonish.
