500 error when trying to view java source file (BB-7139)

I get a http 500 error when trying to view a specific source file, repeatedly.

The url is :
https://bitbucket.org/ansell/sesame/src/321c2d4d2fa0f67105636ad9de5894f6a7a9207d/core/queryresultio/api/src/main/java/org/openrdf/query/resultio/TupleQueryResultWriter.java?at=SES-1669

It seems to be specific to that file, I can open other java files in the same repository/branch without problems.

the error page gave this code as "useful for debugging": 9680c7a17ab24203abbd6e7bd6479f92$722ed0255fee5b450fd4152fd4a48935
