Search generating unhandled exception error

[Stephen Dawson]

In Calibre 64-bit version 1.33 on Windows 7, some searches are generating errors:

ERROR: Unhandled exception
TypeError: 'int' object is not iterable

To reproduce:

Open Calibre
Type "Aubrey" (without quotes) in the Search box
Press Enter
error message is displayed

I think that the error is being generated when anything is searched for without a prefix. For instance, "Series:Aubrey" works fine, as does "Author:Aubrey", but "Aubrey" on its own generates the error. Limited testing suggests the error occurs regardless of the search word or phrase used.
