I added some logging on each call to PicFile constructor:

New PicFile from filename: ICONPGA

It appears to always fail to load the image ICONPGA.

Interestingly, this happens twice. The first time (before the UI starts), the exception is caught.

The second time, (when loading the main game screen for Turn 0, after the setup menus) the program crashes.

Coincidentally(?), ICONPGA is one of the few ICONPG files with both a .PAL file and a .PIC file.

I have a mild suspicion that CivOne is failing to decode the first .PIC file that has a .PAL (palette) co-file.

[misterbeebee]

By removing ICONPGA.PIC and copyingICONPGB.PIC in its place, I am able to start playing the game.

Something must be wrong with my ICONPGA.PIC or with the way CivOne decodes that particular file in my particular version of the game.

I'm not sure which version of the game I have, but my data files are all dated "Dec 17 1991", except for PRODUCT.TXT dated "Jan 5 1992".
