They're not sure of the guy's motivation, but it appears as though he may have tried committing suicide... he used gasoline, some rhumors are that he poured it on himself, lit it, and ended up killing himself.

however, it wasn't necessarily the gasoline fire that killed him, it was the ceiling collapsing on him, including an air freshener that did him hin (apparently).

anyways, like andrew said, it's most likely not an act of terror, but an isolated incident.
