[syslog-ng] Hitting g_assert when using sanitize-utf8 enabled!

[Scheidler, Balázs]

Hi,

Attila is right, it would help a lot to see the original log message and
your glib version. That code path uses a performance hack that relies on a
GLib implementation detail. Either the glib behaviour has changed or
another assumption fails, but just looking at the code I don't know what
might.
