Python LLDB script

Using a Python script in LLDB to redirect the debugger output to a file causes
lldb to crash.

Steps to Reproduce:
===============
1) Start lldb with an executable
2) Load the attached python script
lldb) command script import ~/Desktop/po.py
3) Create a breakpoint somewhere interesting
4) Run the executable
5) At the breakpoint, write some frame data using the Python script
lldb) print_to_file fr v param.blah
6) Re-run the previous command or dump another frame variable
lldb) print_to_file fr v param.blah
7) Core Dump - "segmentation fault (core dump) lldb <executable path>"</pre>
