Pull request is NOT accessible

I cannot access the last pull request we have in one of our repositories, is there any problem in the servers?

The pull request is: https://bitbucket.org/ccsw/selecta/pull-request/36/cambios-de-este-mediod-a-a-adir-checkbox

And the Error 500 page shows the following string as "useful information"
8f87d6fb6012470b94340a14760d4bea$ddce030aac1308e34ce5405428a745ef

Thank you in advance...
