just a guess - but Sony has been moving ahead with standards compared to Premiere Pro's ability to implement them. Not by much but enough to cause occasional problems. Does the mxf file play correctly in Catalyst Browse (free download from Sony) ? If it does the clip is ok.
A way around is to trans code the clip. If you have CC you can test with Media Encoder to put it in another high end format and then even try trans coding back to Mxf (with a content type you can handle). An alternative is Handbrake.
The reason this *might* work is that the Application that is parsing the essence might have a different approach to handling what it perceives as an error. So one might plough on where the other gives up (e.g. hangs, green screen ...).
This process might not result in a perfect copy but it is the pragmatic option.
