BUG: FatalError when exporting layer comps to pdf file in PhotoShop CS6

Question

I've been starting to use the File -> Scripts -> Layer Comps to... frequently--it is great for sharing files with clients.
When I used File -> Scripts -> Layer Comps to Files (type: pdf, "selected layer comps only" with about 6 of 12 comps selected) today I got the following error:
"FatalError: General Photoshop error occurred. This functionality may not be available in this verison of Photoshop. - <no additional information available>"
The only other notification I get for this document is a missing font upon opening, which I do not imagine would be a problem.
I am on the latest version of PhotoShop CS6 as confirmed by my CreativeCloud app.
My MacBook Pro is pretty generously outfitted and updated: OS 10.9 (latest update), 16GB RAM, over 100GB free HD space, 1GB VRAM.
I haven't had a chance to do repeated tests to get it to fail like this again as I'm on a deadline so I had it do the same process but exporting ALL layer comps and I removed the unwanted pages in Acrobat Pro.

Answer 1

So I've found a bit in the script that I think might be it (below).  Can I remove that whole bit?  Or would changing the 4 to a 0 do the trick (I tried and it didn't do anything)... Sorry, but I'm not a coder so don't really know if I'm barking up the wrong tree or not.
Thanks
for ( compsIndex = 0; compsIndex < compsCount; compsIndex++ ) {
                var compRef = docRef.layerComps[ compsIndex ];
                if (exportInfo.selectionOnly && !compRef.selected) continue; // selected only
                compRef.apply();
                var duppedDocument = app.activeDocument.duplicate();
                var fileNameBody = exportInfo.fileNamePrefix;
                fileNameBody += "_" + zeroSuppress(compsIndex, 4);
                fileNameBody += "_" + compRef.name;
                if (null != compRef.comment)    fileNameBody += "_" + compRef.comment;
                fileNameBody = fileNameBody.replace(/[:\/\\*\?\"\<\>\|\\\r\\\n]/g, "_");  // '/\:*?"<>|\r\n' -> '_'
                if (fileNameBody.length > 120) fileNameBody = fileNameBody.substring(0,120);
                saveFile(duppedDocument, fileNameBody, exportInfo);
                duppedDocument.close(SaveOptions.DONOTSAVECHANGES);
