all this dissapeared when i completely deleted the plugin and copied it back..
before that there were some files from older version..
now everything works fine..

so, this is what i faced:

when i try to copy anything to the remote side, first i get a copy dialog with "copy aaa.bbb to: plugin:".
the next dialog is Copy "copy aaa.bbb to: /remote/path/*.*".
in russian translation it is displayed as "reading folder" in the title, and "modifying folder" over the text box.

after i press enter different things happen.
either "copying to remote side failed. invalid access to memory", or something like "list out of bounds -1).

on creating or deleting folders the same things happened a few times (list index...)

in the russian translation the "create folder" dialog looks terrible..
