Anyone notice the bug in the latest Stargate show?

Just wondering if anyone noticed the bug in the latest Stargate SG1 series where the Jaffa (or whatever name the warrior people have) used the weapon to destroy all life on the one planet via the stargate. SG1 escaped by getting beamed out at the last second. Anyway, if you happened to tape it to watch it later, you will hear all life has been destroyed and see a scene where only clothing remains where people used to be. Then suddenly if you watch close, a large bug or two comes zigging zagging into the picture.

Now that's what I call a bug in the show. Anyone notice other obvious bugs or errors in the show?
