Also happening in 17.04. Started happening after a fsck repair following a power failure. Could be related to lost/corrupt files.
Running tracker-extract manually on file shown in syslog gives the following. roger@dragon:~/Documents/Old Stuff/Camtasia Studio$ tracker extract --verbosity=detailed visualimpact.avi Tracker-Message: Starting tracker-extract 1.12.0 Tracker-Message: General options: Tracker-Message: Verbosity ............................ 2 Tracker-Message: Sched Idle ........................... 1 Tracker-Message: Max bytes (per file) ................. 1048576 Setting priority nice level to 19 Loading extractor rules...

"The actual extraction is done by a separate process. This is done to isolate the calling process from any memory leaks or crashes in the libraries Tracker uses to extract metadata." -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to tracker in Ubuntu. https://bugs.launchpad.net/bugs/1504079 Title: tracker-extract crashed with SIGSEGV in gst_video_info_to_caps() Status in tracker package in Ubuntu: Confirmed Bug description: i need ProblemType: Crash DistroRelease: Ubuntu 15.10 Package: tracker-extract 1.4.1-1ubuntu2 ProcVersionSignature: Ubuntu 4.2.0-14.16-generic 4.2.2 Uname: Linux 4.2.0-14-generic i686 ApportVersion: 2.19-0ubuntu1 Architecture: i386 CurrentDesktop: Unity Date: Thu Oct 8 16:04:40 2015 ExecutablePath: /usr/lib/tracker/tracker-extract InstallationDate: Installed on 2015-09-13 (25 days ago) InstallationMedia: Ubuntu 15.04 "Vivid Vervet" - Release i386 (20150422) ProcCmdline: /usr/lib/tracker/tracker-extract ProcEnviron: LANGUAGE=en_US PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash SegvAnalysis: Segfault happened at: 0xad14eb08 <gst_video_info_to_caps+40>: mov (%eax),%eax PC (0xad14eb08) ok source "(%eax)" (0x0000007c) not located in a known VMA region (needed readable region)! destination "%eax" ok Stack memory exhausted (SP below stack segment) SegvReason: reading NULL VMA Signal: 11 SourcePackage: tracker StacktraceTop: gst_video_info_to_caps () from /usr/lib/i386-linux-gnu/libgstvideo-1.0.so.0 ??
