#1015: Ufunc generates AttributeError on object arrays
--------------------+-------------------------------------------------------
 Reporter:  wesm    |       Owner:  somebody
     Type:  defect  |      Status:  new     
 Priority:  normal  |   Milestone:  1.3.0   
Component:  Other   |     Version:  none    
 Severity:  normal  |    Keywords:          
--------------------+-------------------------------------------------------
 This error is very unintuitive for end-users, arrays formed from SQL query
 results can frequently end up as object arrays by accident.

 In [15]: arr = np.random.randn(100).astype(object)

 In [16]: np.log(arr)
 ---------------------------------------------------------------------------
 AttributeError                            Traceback (most recent call
 last)

 H:\workspace\Python\src\<ipython console> in <module>()

 AttributeError: log

 Same AttributeError is raised for other ufuncs
