The reason for the assert is that the transport manager can't find the transport that was passed to it (transport = sending account).

This doesn't happen for me, so please answer the following questions:

What is the name of the sending account you are using?
How did you send the message? Directly from the composer or by queing it first?
Are you using completely new configs or did you re-use your old configs from KDE3?
Is this problem reproduceable with a clean config? If so, please add the minimal steps to reproduce here. If not, your config file would probably help, please attach .kde[4]/share/config/mailtransports (strip the passwords first!).

Thanks.

weird I swear I was getting this on both computers...
I just tried here making sure I had a clean config and it works fine
I'll try on the work pc tommorow, but I bet I had a config from kde3 there by
mistake also
