Weird. The sqlite3_value_free issue sounds like maybe BricsCAD is bundling sqlite (tracker links against sqlite as well) and then the dynamic linker ends up resolving tracker's sqlite symbols to the wrong sqlite library and that causes things to blow up.
Sounds like it's safest to unpush this update for now to avoid weird issues with 3rd party programs.
@ozeszty Oh, that's a good point (sorry, I missed your comment earlier). I am not entirely sure what would be the best solution here though. To avoid the duplicate indexers on KDE, I guess a solution would be if libtracker-sparql package stopped recommending tracker package -- but at the same time, doing so would regress the search in gtk file chooser dialog on KDE.
