As an alternative, I've just been running SQL commands against the EventLog table. You can get collated information on the error message from there and the stack trace and other information can be found in the LogProperties field.
It appears my module created the infamous "DotNetNuke.UI.Skins.Skin.GetSkin(Me)" error found here. Unfortunately my situation appears to be somewhat different as the only recommended solution does not work for me. Looks like it's time for another DNN wipe.
