This fixes PR python/16487.
The bug here is that the function-name-handling code in py_print_frame
had a small logic error (really a misplaced closing brace). This
error could lead to a Py_DECREF(NULL), which crashes.
This patch fixes the bug in the obvious way.
Built and regtested on x86-64 Fedora 18. New test case included.

* python/py-framefilter.c (py_print_frame): Don't call Py_DECREF

PR python/16487:
* gdb.python/py-framefilter.exp: Add test using "Error" filter.
* gdb.python/py-framefilter.py (ErrorInName, ErrorFilter): New
classes.
apply_frame_filter calls ensure_python_env before computing the
gdbarch to use. This means that python_gdbarch can be NULL while in
Python code, and if a frame filter depends on this somehow (easy to
do), gdb will crash.
The fix is to compute the gdbarch first.
