Tantalums just don't appreciate being installed full stop, I've seen them do that when they were fitted correctly too..

Tantalums do not appreciate being installed backwards.  ::)

Indeed! They don't always show obvious signs of failure such as on your picture though. They usually fail as shorts. On occasion, I'ven seen SMD tantalum caps soldered backwards and shorting power supplies on the first try. The caps weren't burnt externally, but probably because the power supplies were shut down immediately after.

800W Ohmite resistor, too little heatsink, the poor thing couldn't take it any longer.
