Hello Sangu, if you can reproduce this every time, are you able to attach the file that causes this?

It looks like tracker-extract is extracting a PNG here and you should be able to reproduce using:

  /usr/lib/tracker/tracker-extract -v 3 -f $file

If you need to figure what the file is called, you can set the config to log verbosely using:

  tracker-control --set-log-verbosity=debug

the log should be in ~/.local/share/tracker/tracker-extract.log - or running tracker-extract as above with -d should allow you to start it BEFORE you start the miner-fs so you can watch requests coming in.

Let me know if you need more information here.

Comment 3 Martyn Russell 2012-04-30 15:01:19 UTC

Hello Sangu,

What version of libpng are you using?

I am unable to reproduce this bug with libpng3 version 1.2.46-3ubuntu4 (on Pangolin).
