Strange bug with sum an evalf

I could not find any place to submit bug reports to Maplesoft, so I'll post this here: When evaluating the divergent sum sum((1+exp(n))/(exp(n)-1), n=5..infinity); Maple 11 just returns it unresolved. Then I tried evalf(%); and got the 2.700548143. When starting with a different index then 5 evalf does nothing (which is probably the correct behavior) and when summing only finitely many terms evalf works correctly (though it is surprisingly slow). Here is a screenshot of a sample session. I'm using Maple 10.01 Linux 64bit version (on Ubuntu Linux 7.10, 64bit).
