Client reports 405 error when pushing files with no basename

Description of problem:
the client reports what files are planning to be transferred on push though, if the target directory contains .pot say, it isn't included in the list but the operation simply failed like:
pushing source doc to server
Operation failed: Error status 405 Method Not Allowed returned

To retry from the last document, please set the following option(s):

--from-doc ""

.
Execution failed: Error status 405 Method Not Allowed returned

If kinda "no name" is wrong, the client should ignore a dot file.
