[CentOS] LD_LIBRARY_PATH issues

Here is the thing. All workstations in the network have the /etc/profile modified and set up to call a profile script in the network that sets up variables that we need here. Here $LD_LIBRARY_PATH and other variables get set, fixed, or modified to support our development process. The weird thing is that while in a TTY the $LD_LIBRARY_PATH is fine and retains its value. But if I log in to the gui (KDE, GNOME) then the $LD_LIBRARY_PATH is blank. I have greped the entire disk I can't find where is the $LD_LIBRARY_PATH is being overwritten, if that is what is happening.

Does anyone knows what's going on here?
