[sip-comm] SIP account frozen after the invalid value


Hello all,
I have just joined this very intersting project and would like to
submit an issue.
When I fill in an SIP account with an invalid values
(Sip_account.png), there is an error window (Null_error.png) that is
not possible to close. The whole application is frozen.

I use Fedora Core 8, java version "1.5.0_14"

Do you agree it is a bug?



P.S. Is there a guide describing how to set up and configure
sip-communicator with openser?
