There is no related bug. I noticed the crash by introducing an invalid spice URL.
The spice_channel_get_error() was introduced without guarantee when it will
return an error, you must always check if it is non-NULL. (Historically, errors
have been returned via SpiceChannelEvent, but an enum isn't flexible enough
and can't map all possible underlying GErrors details..)
