These criticals are due to the tracker-store crash which Philip fixed.

I checked this code and it looks sane to me. Perhaps we need to re-run this
in valgrind to see what happens.

Hi,

Am not sure if this is a Debian-only problem:

<START>
Tracker-Message: Crawling recursively directory
'/usr/share/applications'

This warning is about tracker-store crashing which Philip fixed. I was
seeing this too.

Are you still getting these errors since the tracker-store bug was fixed?


I'm running cd3de5b8be1309da05ea667bbb6d2a12862a12a2 which is
"tracker-extract: Fixed the jpeg extractor to use
TrackerSparqlBuilder", so yeah that's some commits after -store crash
was fixed.


Here's what I'm now getting:
