Updated system-config-printer packages that fix two bugs are now available for Red Hat Enterprise Linux 6.
The system-config-printer package contains a print queue configuration tool with a graphical user interface.
Previously, displaying tooltips while being in a main loop recursion caused the system-config-printer utility to terminate unexpectedly. To prevent system-config-printer from crashing, displaying tooltips is now avoided during the main loop recursion.
Python bindings for the CUPS library were not reliable when threads were used. In particular, a single password callback function was used instead of one for each thread. This, in some cases, caused the system-config-printer utility to terminate unexpectedly with a segmentation fault. With this update, thread local storage is used for the password callback function in Python bindings for the CUPS library.
All users of system-config-printer are advised to upgrade to these updated packages, which fix these bugs.
