A bug that advanced search processing might fail

[userlocalhost]

There is a bug that internal error would be happened by following procedures.

1. Create an Entity "E1" with an "array_string" typed attribute that is named by "attr".
2. Create an Entry "e1" and set arbitrary value to attribute "attr".
3. Edit Entity "E1" and delete attribute "attr", then save it.
4. Edit Entity "E1" and add a "string" typed attribute that is named by "attr".
5. Edit Entry "e1" and save it without any input.
6. Send request of advanced search of "E1" with attribute "attr".

After the procedure (6) following exception would be happened.

print('(%s|%s) %s' % (name, val['value'].class.name, val['value']))

I close it because that is because of my test environment debug code.
