After update all attachment file begin with \n=\x0A
And it displayed wrong.
I am use version trunc, before all be ok :)
P.S. Sorry for my English
Its working fine for me (r3725) what type of file are trying to upload, what is the name, and are you using the default skin?
I am dont use defaul skin.
File type - all type.
Problem not with upload, problem with downloading of files, thus it is not important whence to me the letter with nesting comes. All nestings are downloaded with line feed as the first string.
I am update roundcube, last trank, problem fixed.
