On XUbuntu 12.10, anything that isn\'t a DDS or a PNG in RGBA format makes the VS engine go kookoo with the Privateer: Parallel Universe assets (but not with the native VS assets, strangely enough). On Fedora OTOH, there isn\'t a hint of trouble. From a cursory analysis, the only difference is that XUbuntu 12.10 uses libpng1.2, whereas Fedora 17 uses libpng1.5.
I figure that there\'s a higher probability that people who want to build VS will be using Ubuntu rather than Fedora, so this is intended to be the tracker issue for this rather strange phenomenon, which nonetheless is bound to have a logical explanation. I hope.
