[PATCH] server/process: Fix logging issues where only the first message was displayed

[Richard Purdie]

I realised only the first logging message was being displayed in a given
parsing process. The reason turned out to be the UI handler failing
with a "pop from empty list". The default handler was then lost and
no further messages were processed.

Fix this by catching the exception correctly in the connection writer code.
