5.5.1 bug with directory ending with the period (.) char

On remote list, every directory ending by the period (.) char will display only the last char.

Try to create "t.e.s.t." and you will end up with "t" only and you won't be able to rename/delete.

It was working fine with previous version (I think I was running 5.1.4 before upgrade)

Thanks for your report.

I'm sending you a dev build for testing.
