Description

Rough code:

with rados.ReadOpCtx(metadata_io) as rop:
    omap_iter, rval = ioctx.get_omap_vals_by_keys(rop, ("foo,))
    ioctx.operate_read_op(rop, "my_object)                        # If you omit this line ...
    result = list(omap_iter)                                      # ... then this line will segfault

I stumbled upon this when writing a script and not paying enough attention to how to use the API (using Kraken)
