[Libguestfs] [hivex] Segfault for an integer value to node_set_value

[Peter Wu]

Hi,

When an integer argument is passed as value, node_set_value
segfaults. Reproducer is at the end of this message

The backtrace points at hivex-py.c, function get_value. While obj
is non-NULL, `bytes = PyUnicode_AsUTF8String (obj);` returns NULL.

Kind regards,
Peter
