Safe handle has been closed

Hey, I got the following exception when my program tries to open a tapi line. It works fine for all other users but we always get this error for this user/tapi line. We've tried to remove and then add the user from/to the security group in Cisco Call Manager but the issue remains.

I've done a bit of searching and found issue 11483, which appears to be similar... Does anyone know if I should try the approach stated in 11483?

Thanks
