<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">f->len is not good here. Frame can very easily be null within this block of code, and if it is, trying to access f->len will cause a segfault... and in fact, messing about with google voice with the interns today exposed this very problem.
Generally speaking you need to wait for someone internal to give a ship-it before committing code if you have commit access. I don't actually know whether that status of people on reviewboard is actually viewable anywhere, so I guess for now the only real answer to that is that if you don't know, you need to ask on IRC. I'm going to go ahead and fix these items since it's a pretty easy change, but just keep that in mind int he future.</pre>
