I've just upgraded to phabricator rev 18340d9 (to test out the fix recently committed for T7392), and now when searching for "Show Tasks Not Blocked By Other Tasks", I get the error
> **Unhandled Exception ("AphrontQueryException")**
> #1052: Column 'status' in where clause is ambiguous
The error log doesn't appear to be particularly useful, although I'll include it just in case:
```

Looking at D11911, there's nothing that stands out as being egregiously wrong, so I'll leave the diagnosis to you pros. Let me know if I can provide any further diagnostic data, testing, or whatever will help.
