When the ammo dump is blown up at the end, dust falls on Schultz as he is bent down. When he crawls under the table to exclaim that they did blow up the ammo dump, and the view shifts to him, there is no dust on his uniform. When he crawls back and stands up, there is dust on his right sleeve and shoulders.
After Newkirk and LeBeau are done identifying all the various listening devices they have retrieved from Klink's office, they start unloading the various liquor bottles they obtained from Klink's liquor cabinet. Newkirk opens one bottle and sniffs the contents, then lowers the bottle such that the top of the bottle is below his chin. The label is quite visible, facing the camera. There is a cut to a two-shot of Hogan and Newkirk, and now he is holding the bottle with the top level with his eyes, and the label of the bottle facing away from the camera - somewhere between Hogan and Newkirk.
After LeBeau develops the pictures of the documents (still damp), Hogan starts reading them, and picks one up. He notices that they include the Underground's target for the next night, Crump Oil Refineries. Then Hogan drops the picture. Eventually, there is a cut to a two-shot of Hogan and Newkirk, where they discuss identifying Hindmann by having Newkirk attempt to recognize his voice. When Hogan asks if Newkirk thinks he can do so, he replies, "I don't know. I can try." There is a cut to a wide shot of the whole gang, with Hogan now holding a picture of a document. There was never a point during the discussion where Hogan picks up one of the pictures. During the dialog (two-shot) between Hogan and Newkirk, Hogan's hands are not visible, so it might have been possible for him to have picked one up during that conversation, but the way Hogan moves, and the position of his right hand and arm during that dialog, indicate that he is resting his right hand on his right knee.
Near the end, Schultz states that there are 1000 SS troops guarding the ammo supply. This is way too many. At most, there would be about 200 or so guarding the place. Keeping a battalion (about 1000 troops) guarding a single ammo dump at this time in the war is inefficient.
In the scene in Klink's office when Newkirk is trying to break into the safe, the time between when Carter hangs up the phone the first time and it rings again with the same person is too short. In the 1940's, there was no call back button, and you have to manually dial the number on a rotary phone. It would take twice the time that there was between the calls to dial the number.
UPDATE: This is not a goof. Five seconds elapses between Hogan hanging up the telephone (on Carter's behalf) and the phone ringing again. This is sufficient time for viewers to maintain their willing suspension of disbelief at the callback time, particularly if they can maintain their suspension at Carter speaking English and not German.

When Gertrude first shows up in Klink's outer office (at Hilda's desk), she gives Klink a wastebasket full of papers and a box, and tells him to dump the wastebasket, get rid of the box, and bring a broom on the way back. Klink then goes into his office. He is next seen from behind (he is inside his office), and overhears General Burkhalter tell Gertrude that what Klink really needs is a wife. Shortly after, Klink turns and has a broom in his hands. It makes no sense that Klink would go into his office to dispose of the items and get a broom. There is no place for him to dispose of them, and there is no place in his office where a broom is stored. The only other door in Klink's office leads to his private quarters (or maybe washroom - see The Meister Spy (1971), when Major Martin/Hans Strausser uses it to clean up), which would also not make sense for him to use to dispose of the trash and pick up a broom. The only reason he would have been directed to go into his office (instead of exiting the building to dispose of the trash) is so he could overhear the conversation between Gertrude and the General.
Some TV listing data base(s) has/have Casanova spelled 'Cassanova'.
