Every time claws-mail retrieves mail it writes status (NOT error) messages to $HOME/.xsession-errors

Brief sample below:

My current .xsession-errors has accumulated 174614 such messages in 8 days.

Should these messages not be written to a separate log file (and probably over-written each time mail is fetched)?
