Title: gnome-control-center crashed with SIGSEGV in slab_allocator_free_chunk() CUPS Status in gnome-control-center package in Ubuntu: New Bug description: I was adjusting CUPS settings for a network printer and I got a crash notice. I have a Brother MFCL2750DW printer (with the three Brother deb packages installed). The printer is directly connected to this computer, but I was modifying the settings for the NETWORK connected printer to try to track down a random printing issue. (The printer occasionally hangs when printing a multi-page double-sided document.) Opened Gnome Control Center using the "Tools" menu in the top right of the Ubuntu desktop. Devices --> Printers I had just turned OFF the CUPS setting that was sharing all printers connected to this PC. The old printer was shared through this computer and the new one is connected directly to the network. I am looking at the NETWORK printer. (It has underscores in its name: "Brother_MFC_L2750DW_series" and it has a a generic icon that looks like stacked boxes.) I clicked the gear --> Printer Details. I clicked Select from Database I selected the printer from the list. There were two MFCL2750DW drivers listed (At some point the icon changed from the generic network printer icon.) AFTER THIS IS WHERE I BELIEVE IT CRASHED I had already chosen a driver I clicked the button that said "Search for Drivers" Next thing I knew I had the oopsie dialog and the browser opened the bug in launchpad. I know this is old software at this point so feel free to close this if it's already known. Just let me know if you need more info. I plan to upgrade to a newer version of Ubuntu, but I'm waiting for some regressions to be addressed in the LTS.
