Bug in gdb.block_for_pc documentation?

Hi all,
Looks like there is a bug in docs:

*"Function: gdb.block_for_pc (pc)*

*Return the innermost gdb.Block containing the given pc value. If the block
cannot be found for the pc value specified, the function will return None."*
https://sourceware.org/gdb/current/onlinedocs/gdb/Blocks-In-Python.html#Blocks-In-Python


Instead of returning None it throws runtime exception:

gdb.block_for_pc(0)
>> RuntimeError: Cannot locate object file for block.

Thanks,
Roman
