AutoShare Problem to send files from Android to PC

Hi all,
i have a problem to send file from Smartphone to PC. Files which has an underline "_" in their names are showing an error message in Event Ghost. The filetransfer is working with files without underline.
------------------------------------------------------------------------------------------------
Traceback (most recent call last):
File "SocketServer.pyc", line 596, in process_request_thread
File "SocketServer.pyc", line 331, in finish_request
File "SocketServer.pyc", line 652, in __init__
File "BaseHTTPServer.pyc", line 340, in handle
File "BaseHTTPServer.pyc", line 328, in handle_one_request
File "D:\Programme\EventGhost\plugins\AutoRemote\__init__.py", line 444, in do_POST
content = self.rfile.read(contentLength).decode("utf-8")
File "encodings\utf_8.pyc", line 16, in decode
UnicodeDecodeError: 'utf8' codec can't decode byte 0xff in position 0: invalid start byte
---------------------------------------------------------------------------------------------------------

Can somebody help me how can i fix that? The most of the pictures made by a smartphone having underlines so thats not an unique thing from my perspective.
