A service that is not mapped to a display name in oc.statistics.js labels map is displayed as undefined in the servers table. The services table has a fallback for this but it is pretty ugly. There should be a decent label name function.
Christoph, did you mean to leave the text analysis name commented out? Regardless, merged into 1.4.x with rev 15355. Please resolve as fixed and reviewed if you meant to leave that line commented out.
I forgot to uncomment it again. Sorry, the mapping is now back in.
New fix merged into 1.4.x with rev 15404.
