Comment 7 for bug 1378438

The /tmp getting quickly filled up with links to PPD files is treated in bug 1156398.

A workaround for bug 1156398 is to deactivate the system-config-printer applet and/or the system-config-printer D-Bus service by removing the read bits from the appropriate files, for example:

sudo chmod -r /usr/share/system-config-printer/scp-dbus-service.py

Does this solve the problem for you?
