How could we continue debugging? IIUC, process 31377 is started by cupsd itself. Commit 1728c411718e3b358c06561d6e80b47d7b331617 wrapped the cups-filters programs but not cupsd itself. Perhaps we need to wrap cupsd similarly? Could you grep the source of cups itself to see if it contains this ‘gs’ invocation? In the meantime, can you try adding ghostcript to your system profile? That should work around the problem. Thanks, Ludo’.
