Description Christian Stadelmann 2016-04-07 16:02:32 UTC 
When tracker-extract is running, it prints hundreds of warnings to syslog. Some of these warnings include:

Duplicate property or field node

XML parsing failure

libpng error: Not a PNG file

Not a JPEG file: starts with 0x3c 0x21

libpng warning: iCCP: known incorrect sRGB profile

libpng error: IDAT: CRC error

libpng warning: cHRM: inconsistent chromaticities

GIF-LIB error: Image EOF detected, before image complete.


These warnings are pretty useless without printing a filename (path). It would be useful to either not log these warnings at all or to add a path to the syslog output.
Comment 1 Carlos Garnacho 2016-05-06 10:14:45 UTC 
Those specific errors are all from underlying libraries (libxml, libpng, libjpeg, ...), not much we can do about these...

What we do though is warning if no module was able to get information for a given file:
https://git.gnome.org/browse/tracker/tree/src/tracker-extract/tracker-extract.c#n623

Which of course won't help if those warnings don't turn out fatal in those libraries.
