Can't locate timestamp or sequence issue in RTP stream

When viewing RTP streams for the attached file, the RTP Streams window indicates (via the X in the Pb? column) that there is a wrong sequence number or wrong timestamp number, however when I analyze the stream and click “Next non-Ok” it doesn’t show me any errors. Using wireshark 1.8.0, latest pcap build. Please let me know if there’s any further info I can provide.
