That can occur if the program was so fast that it could not be sampled. Try profiling a slower request to see if you get anything. You can also try increasing the frequency.

Nope, whatever page I test (and my app is not the fastest) I get this error. Also upping the frequency doesn't help. In the browser the error looks like this:
Running the command 'bundle exec pprof.rb --text /private/var/folders/7h/y502phtj2b1g8cjs0c173hrw0000gn/T/rack_perftools_profiler.prof' failed to generate a file
Standard error:
Using local file /Users/nico/.rvm/rubies/ruby-2.0.0-p247/bin/ruby.
Using local file /private/var/folders/7h/y502phtj2b1g8cjs0c173hrw0000gn/T/rack_perftools_profiler.prof.
It only appears with mode=objects. Which is the only mode I need unfortunately...

Ah, sorry. I missed the part about it only failing in "objects" mode.
It sounds like this bug in perftools.rb to me. It's been fixed but a newer gem has not yet been published. Can you try installing the gem from git with Bundler?

thx, yes, it works now, but takes ages for a single request... ;-)
