The workaround I ended up implementing is as follows:

private string FormatEventDescription(EventRecord eventRecord)
{
    try
    {
        return eventRecord.FormatDescription();
    }
    catch (EventLogException e)
    {
        return eventRecord.ToXml();
    }
}

This is less than satisfactory, as that XML is not user-friendly, but at least it has all the information needed in case we need to know the original content of the EventRecord. Note the XML doesn't necessarily contain the description string inside, sometimes these events have a list of parameters which are used to fill a message template to generate the description string, so in this case you'll get the raw params.
