I am having this annoying error that I could not solve.. here is my function

def savePicture(pic):
    connection=sqlite3.connect('/home/faris/Desktop/site/site.db')
    db=connection.cursor()
    print type(pic.user.profile_picture)
    db.execute('INSERT INTO pictures (picture_id, caption, created_time, picture_url, link, username,full_name,profile_picture) VALUES (?,?,?,?,?,?,?,?)',
        pic.id,
        pic.caption,
        pic.created_time,
        pic.get_standard_resolution_url(),
        pic.link,
        pic.user.username,
        pic.user.full_name,
        pic.user.profile_picture
    connection.commit()
    connection.close()
except sqlite3.IntegrityError:
    print 'pic already exist'
And here is my Table (Sqlite :D )
-- Describe PICTURES
CREATE TABLE "pictures" (
"picture_id" INTEGER PRIMARY KEY,
"caption" TEXT,
"created_time" TEXT,
"picture_url" TEXT,
"link" TEXT,
"username" TEXT,
"full_name" TEXT,
"profile_picture" TEXT
And this is the error I am having, 
<type 'str'>
Traceback (most recent call last):
File "/home/faris/Desktop/site/cron/pictures.py", line 15, in <module>
savePicture(picture)
File "/home/faris/Desktop/site/db.py", line 36, in savePicture
pic.user.profile_picture
sqlite3.InterfaceError: Error binding parameter 1 - probably unsupported type.
As you see I have printed the type of the "pic.user.profile_picture" and it returned str 
I have also tried using these two functions ( unicode and str ) just to make sure that it is returning a string with no luck..
Any ideas? cheers :D 
                Actually, the hint is in the last line: Error binding parameter 1. Parameter 1 is pic.caption (pic.id being parameter 0, pic.created_time being parameter 2, etc.)
