Is it a little bug in wbemprox?

[Jing Li]

Hi,
  When I ran a simple win32 program just via WMI with query of "SELECT *
from Win32_Directory", wine1.6 crashed. And when I checked the related code
I found that the function of "static UINT seed_dirs( struct dirstack
*dirstack, const struct expr *cond, WCHAR root, UINT *count )",
in dlls/wbemprox/builtin.c:1086, accessing cond's member without checking
if it's NULL! Unfortunately a NULL is passed to it. That's why my program
crashed.
  It's a bug, right?
