While running an automated test using evolution, if it becomes disconnected
from the back end, each message that it tries to send lands in the "Outbox".
When a message is dumped in the outbox, evolution tries to send all the
messages that are there, but if no connection can be made to the back end, an
error window is displayed saying:

"Evolution Error"
"Could not send message"

The problem is that for each item in the outbox, a seperate line "Could not
send message" is displayed in the error window. This causes the error message
to quickly become larger than the screen size, and makes it difficult to close.
