Description Laurent Bonnaud 2014-06-11 10:14:39 UTC 
Hi,

each time I log in tracker-miner-fs crashes.  Sometimes it crashes with this crash:

  https://bugs.launchpad.net/ubuntu-gnome/+bug/1327131

and other times it crashes with this crash:

  https://bugs.launchpad.net/ubuntu-gnome/+bug/1324808

Note that my system has the following environment variables that may reveal dormant bugs:

MALLOC_CHECK_=3                                                                                                          
MALLOC_PERTURB_=117                                                                                                      

The above bugs have all necessary information, but here is a quick summary:

 - tracker version: 1.0.1

(I don't know if you get notified of bug updates in launchpad, so here is the latest information:)

Today I had to log in again and the crash occurred again:

 - running /usr/lib/tracker/tracker-miner-fs -v 3 -s 0 led to a reproducible crash

 - unsetting the MALLOC_PERTURB_=117 variable allowed tracker-miner-fs to complete without crashing

 - running /usr/lib/tracker/tracker-miner-fs -v 3 -s 0 again led to no more crash

Hello Laurent, I will check this out and see if I can reproduce it. Thank you for the details, appreciated!

Hmm, didn't crash here :/

I am on a different branch though, so I will test that next.
Out of interest, does this happen for the same file or random files?

The backtrace looks like it's querying for a specific file.

tracker-miner-fs crashed each time on the same file the first time I was able to reproduce the crash.

The second time too, but it was a different file (and much earlier in its directory tree walk).

Ah, can you attach the file here perhaps so I can test with it?
I haven't been able to reproduce this crash yet :/

Sorry but the crash is seldom occurs on the same file.  Recently it occurred on another system and another homedir with a completely different set of files.

Here is the latest instance of this crash:

  https://bugs.launchpad.net/ubuntu-gnome/+bug/1387217

on an Ubuntu 14.10 system and with tracker 1.2.3 (that recently arrived in the GNOME PPA).

I believe this is a duplicate of bug #739237, I will try to release with this fix in 1.0.x and 1.2.x soon after hearing back from Philip in the actual bug report.

Thanks.
