Visible crew/equipment: During the last scene in the infirmary, Bashir has a word with O'Brien about Garak's condition. Then, just as O'Brien walks towards Garak, on the console's reflective surface, we can see the reflection of the moving boom mic (beside the ceiling's black stripe pattern) at the bottom of the screen.

Visible crew/equipment: After Garak takes out the first Cardassian while hiding in the broken stasis chamber, when it cuts to Nog walking towards O'Brien, there are three tape marks visible on the floor behind O'Brien. (00:25:25)
Chosen answer: No. He's given his name, that's all. Nothing there that might lead to a paradox. If he's gone into detail about his time travelling, that might cause an issue or two, but simply stating his name does nothing.
