Mnemosyne wont start

[Gnome]

I get this error when starting mnemosyne:

"Error in config:

Traceback (innermost last):

File ,,mnemosyne\libmnemosyne\configuration.pyo", line 187, in load

EOFError"

and

"An unexpected error has occurred.

Please forward the following info to the developers:

Traceback (innermost last):

File "mnemosyne", line 155, in <module>

File "mnemosyne\libmnemosyne\_jnit_.pyo", line 167, in initialise

File "mnemosyne\libmnemosyne\_jnit_.pyo", line 247, in activatejromponents

File "mnemosyne\libmnemosyne\logger.pyo", line 175, in archive_old_log

KeyError: 'upload_science_logs'"

then the program quits.

Deleting config fixed it of course.
