simple-scan, scanimage and xsane all getting this: $ scanimage Output format is not set, using pnm as a default. bugchk_free(ptr=(nil))(a)modelinf.c(464) Aborted (core dumped) Presumably it's from a library. Anyone else getting this? I don't see any reports on BZ. poc

Run it under gdb and when it crashes do “bt” to see what lib it is in. Barry

That would explain why others aren't seeing it. I'm going to remove that and attempt to configure the opensource driver. I did this not long ago but have recently installed a new all- in-one printer/scanner, so that looks like the culprit. poc
