Audio doesn't sync after roundtrip to DAW

Here's one I've never run into before. I done audio post on over 100 TV shows that were cut in FCP and never had this problem.
Here it is, client cuts project in FCP 7, true 24p prores. Exports and gives me OMF and exported video. Load into Digital Performer 8.05. Everything lines up frame rate is set to 24, mix. Export stereo audio track, client puts in onto timeline, audio starts drifting and after 50 minutes its ahead of video by a good two seconds. Confirm that file on time line is definitely ahead, properties says file is 50min 9 seconds long.
Look at audio file in quicktime, it say file is 50min 12 seconds long, this is the same length as my DAW says the file should be.
Put reference movie and audio file into Premiere CC and it lines up perfectly 50.12.
Go back to FCP and set audio playbsck speed to 59.12 which is 99.9 percent. File lines up perfectly with video. So there's a .1% speed difference. What gives.
We've checked every setting, sequence, video, audio it all looks correct.
Any ideas? We're stumped. We've found a workaround but I'd like to know if we're doing something wrong or what.
