Bug Description
Under certain circumstances the CUPS library can invalidate the pointer to the structure describing the available printers. When this happens, attempts to print via CUPS in an application can lead to a crash due to a lack of checking in the QCUPSSupport code. The attached patch works around this problem by adding checks to avoid the crash but cannot, of course, do anything about the invalidation of the printers structure.
The patch has also been submitted upstream, without progress: https:/
