I've just released system-config-printer 1.3.9. Here are the changes:
* Updated translations.
* Improved output from check-device-ids script.
* Don't warn about changed cupsGetPPD3 behaviour in CUPS 1.5.3.
* Avoid temporary file leaks.
* Handle file disappearances when caching PPDs (bug #786232).
* Fixed several debugprints (bug #785581).
