I tested my 12.04 installation with apparmor disabled in grub for printing and it also segfaulted. However, this time it is not the printdriver, but libpthread - see below
janos@andraslinux:~$ dmesg | tail [ 56.157663] composite sync not supported [ 56.614874] composite sync not supported [ 56.614886] composite sync not supported [ 57.031522] composite sync not supported [ 57.031534] composite sync not supported [ 57.501989] composite sync not supported [ 57.502001] composite sync not supported [ 121.161899] firefox[1798]: segfault at 4 ip 15684564 sp bfcbc3e0 error 4 in nouveau_vieux_dri.so[15676000+2f000] [ 121.171388] firefox[1801]: segfault at 4 ip 00a56564 sp bf93ea90 error 4 in nouveau_vieux_dri.so[a48000+2f000] [ 461.056973] printdriver[2199]: segfault at 0 ip (null) sp bff4987c error 4 in libpthread-2.15.so[110000+17000] janos@andraslinux:~$ I'm going away for a week now. Will check status of this bug when I come back. Hopefully, we can find a solution. One more thing, the uname -a in my 12.04 is the following: janos@andraslinux:~$ uname -a Linux andraslinux 3.2.0-45-generic #70-Ubuntu SMP Wed May 29 20:11:31 UTC 2013 i686 athlon i386 GNU/Linux janos@andraslinux:~$ I also run updates on 12.04, and will keep both distributions alive until my scanner and printer works. At that point I'll keep only 13.04. Presently scanner works on 12.04 and printer works on neither. My old FC3 installation has both the printer and scanner working, but the system is all messed up, so I use it as a sanbox. I use there twm as window manager and emlfm for files. Thanks again for your interest in helping with this issue - and at the same time, hopefully, make Ubuntu better.
