I'm also running into a segfault in compare_by_display_name(). A little more info on a use case that can cause the issue:
I'm trying to browse the Windows network in nautilus. I go to Places->Network and go into the Windows Network directory. All the workgroups on the local network appear, and I try to enter one of them. At this point nautilus hangs for a while and/or crashes in compare_by_display_name(). If I run smbtree -N in the terminal, I see a bunch of servers and clients in the offending workgroup. Normal Ubuntu clients (not set up for serving) tend to appear as well. If one of the Ubuntu clients has a hostname that is too long to be automatically converted to a NetBIOS name, it shows up in the smbtree -N output with a blank NetBIOS name. Example: \\ really-long-name-of-computer server (Samba, Ubuntu) This blank name is what causes this bug in nautilus. If I go into the offending machines and give them a custom short NetBIOS name in /etc/samba/smb.conf, and restart nmbd on them, the problem goes away and I can browse the Windows network just fine. Perhaps compare_by_display_name() is not handling a NULL or empty string correctly? Either way, it looks like nmbd is auto-generating an empty name, so I would argue that it has a bug that is indirectly causing this bug at the same time. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1280867 Title: nautilus segfaults in compare_by_display_name() Status in Nautilus: Confirmed Status in nautilus package in Ubuntu: Triaged Status in nautilus package in Fedora: Unknown Bug description: samba, Ubuntu 14.04 (alpha) ProblemType: Crash DistroRelease: Ubuntu 14.04 Package: nautilus 1:3.10.1-0ubuntu4 ProcVersionSignature: Ubuntu 3.13.0-8.28-generic 3.13.2 Uname: Linux 3.13.0-8-generic x86_64 NonfreeKernelModules: nvidia ApportVersion: 2.13.2-0ubuntu4 Architecture: amd64 CurrentDesktop: Unity Date: Sun Feb 16 22:44:08 2014 ExecutablePath: /usr/bin/nautilus GsettingsChanges: b'org.gnome.nautilus.list-view' b'default-column-order' b"['name', 'size', 'type', 'date_modified', 'date_accessed', 'owner', 'group', 'permissions', 'mime_type', 'where']" InstallationDate: Installed on 2014-02-15 (1 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Alpha amd64 (20140214) ProcCmdline: nautilus -n SegvAnalysis: Segfault happened at: 0x4bef0a: movzbl (%r12),%ecx PC (0x004bef0a) ok source "(%r12)" (0x00000000) not located in a known VMA region (needed readable region)! destination "%ecx" ok SegvReason: reading NULL VMA Signal: 11 SourcePackage: nautilus StacktraceTop: ??
