Login script loading Safari for some reason?

We have a bash login script which does a bunch of housekeeping each time a user logs in to ensure they get connected to their network storage area etcetera, but one thing we're finding is that as well as doing the things it's supposed to do, it also randomly loads a blank Safari window.

Can anyone suggest either a) how we can find out why it is doing this or b) how to stop it doing this?

The script is as follows:

#!/bin/bash

# Get logged in user, the official Apple-approved way
loggedInUser=`python -c 'from SystemConfiguration import SCDynamicStoreCopyConsoleUser; import sys; username = (SCDynamicStoreCopyConsoleUser(None, None, None) or [None])[0]; username = [username,""][username in [u"loginwindow", None, u""]]; sys.stdout.write(username + "
");'`
echo "Logged in user is $loggedInUser"

(also, if anyone knows of a better way to handle the messaging I'd be interested. The reason I stack up all the messages at the start in reverse order is that killing one to uncover the next one reduces the screen-flashing effect that you would get if you just start one, kill it then start another one, and also ensures that the user can't start using the Mac until the login script is finished working)

If you start the new window before you kill the previous one you shouldn't get the flashing effect.
The other feature that is quite nice is the -timeout option.

Another way of doing messages that I use is with a loop that reads a log file and displays the last message. Then any time you want to change the message you just echo to the end of the log file, in this instance I am using the JAMF ImagingScripts.log file, but you could use anything. I generally have it running as a script called from a LaunchAgent or LaunchDaemon that disables itself before launching the loop so that it disappears after a restart, this allows you to be doing anything you like as part of a another script and then just firing dialogue information to the agent when you want to change the message.
Basically it opens a new windows over the old one and the background one expires silenty behind it a second later.

while :
do
Status_Mark=$(date +"%H:%M:%S")
Status_Message=$(tail -n1 /Library/Logs/JAMF/ImagingScripts.log)
/Library/Application Support/JAMF/bin/jamfHelper.app/Contents/MacOS/jamfHelper -title "Please do not use or power off" -heading "STATUS   ${Status_Mark}" -description "${Status_Message}" -lockHUD -timeout 10 -windowType utility -windowPosition ll &
sleep 9
done

Sorry no idea on the Safari launch, although maybe the Papercut installer at the end as you can't see from here what that is trying to do and it might be trying to open a registration page or something?

I've just checked actually and the login script may not be responsible for the Safari issue; once I quit Safari and log out, it doesn't seem to happen again on subsequent logins. There's nothing in the Login Items so I wonder if it could be something in the default user profile template? Any idea how I would check that?

Also on a somewhat related note, is there a way, either in a script or in the default user profile template, to make Chrome the default web browser?
