Description:
------------
Our Server is: Windows Server 2008 R2 Standard
Running: 
- IIS 7.5
- MSSQL 2008 R2
- php-5.4.4-Win32-VC9-x86

We narrowed the error down to a select query we perform.
Query ex. = SELECT [ID], [NAME], [THUMBNAILPHOTO] FROM [DBNAME]

When we include a text field ([THUMBNAILPHOTO]) in the select query we receive 
the mentioned error.
If we just select [ID], [NAME] then it works fine. We've tried to change the 
field [THUMBNAILPHOTO] from to text to varchar(max) but no difference there.
The content of the field [THUMBNAILPHOTO] is a base64_encoded string.
If we put in less then 300 characters then it would also work fine.
