To answer the easiest question first: try
se4@malfador.com for bug reports.
Next, the SE4G patch 2 overwrites a number of files (the whole point of a patch, after all); there should be a file called "DataFileHistory.txt" that will list all altered data files (of course, looking at the files listed, none of them should be causing this error). In addition, looking at the "InstallLog.txt" file shows that the "path.txt" file gets overwritten as part of patch 1.78. So you may want to double-check and make sure you're using the right mod folder.
Finally, having a "generic" Version of the new ship pictures (or at least using an alternate bitmap that already exists) will also help if you make a mistake and choose the "wrong" shipset (i.e., one that doesn't include your special hullsize pictures) when you start a new solo game.
OT BTW - nice references to "The King and I" with "'tis a puzzlement". And that "...no old, bold space jockies" sounds familiar - I think there's a line "...no old, bold wizards" in the Bakshi movie "Wizards"?
