All of a sudden, I face the issue of QGIS (2.18.15, and 2.14.21 as well) crashing when: - activating layers in the map view from previously saved files. - changing the styles / symbology of vector files, eg. categorizing after certain attributes by finally pressing 'OK'
I tried to reinstall qgis (sudo apt-get purge --autoremove qgis; sudo apt-get autoremove qgis). Furthermore, I tried to start it without loading plugins. Without success.
I currently run QGIS 2.18.15 on Debian 9.
I would like to fix this issue (and learn how it occured).
Addendum: Raster clipper doesn't work with masks from vector files.
