I'm running into an error where the database preset is not importing templates, but it is importing the fields. if I try to import the buzz preset (http://moodle.org/mod/forum/discuss.php?d=84050#p371801 ) with debugging set to all I get the following error:

Notice: Array to string conversion in C:\Program Files\Apache Group\Apache2\htdocs\Moodle\moodle19\lib\datalib.php on line 28
Incorrect integer value: '' for column 'notification' at row 1

It seems that the notification field requires an integer value and will not accept a Null value (like the one being passed). This causes the import to fail (but it actually displays a message saying that the preset was applied successfully)

I've attached a screenshot of the error.
I'm seeing this on Moodle 1.9+ (Build 20080410)
