[llvm-dev] Buildbot can't submit results to LNT server

[Chris Matthews via llvm-dev]

Hi Diana, 

I have seen that issue on some other bots too. I will fix it this week. It is something about how MySQL treats character encodings differently than Postgres. We are checking for the value in the table beforehand, and this logic triggers if the name is not found, but obviously that is not working!
