Read about "NIM085504" in this: http://downloads.esri.com/support/downloads/other_/102-IssuesAddressedList.pdfThat looks like it might be the problem - restricting the Near search to 50m is limiting the features to one point and one polygon. Removing the 50m radius means the tool now completes. Hopefully I can get the update soon so I can return the 50m restriction (I've added a select and delete based on any feature > 50m, which gives the same result but takes a bit longer to process).
Could that perhaps be the issue? 10.2 is resolving an issue where the Near tool isn't working properly on inputs of 1 feature.
Just came across my mind while reading the PDF a week or so ago, hopefully it answers your question.
