Almost trivial fix

[Sergio Villar Senin <svillar igalia com>]

Hi,

find attached the fix to the issue described here:
http://tinymail.org/trac/tinymail/ticket/35

There were some possible fixes, I just took one, to add an if.

Take into account that there is still a problem (talking from MUA
developer POV) the exception is lost in this method, so there is no way
in the client to know what happened.
