    avoid python exception in FrameDecorator.py
    
    This fixes a bug in FrameDecorator.py.
    
    FrameVars seems to assume that Frame.block can return None if there is
    no block.  However, it actually throws an exception.
    
    I saw this bug while developing a frame filter, but unfortunately I
    don't know how to reproduce it.  It seems to me that the SAL tests in
    _is_limited_frame should exclude the bad cases; and in my attempts to
    write a test they do.
    
    Nevertheless I think the fix is reasonably obvious and ought to go in.

    fix erroneous error-handling in frame filter code
    
    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.

    	PR python/16487:

    	on a NULL pointer.  Move "goto error" to correct place.

    	classes.

    fix crash in frame filters
    
    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.
    
    Built and regtested on x86-64 Fedora 18.
    New test case included.
