I was drawning lines of a sewer network using the snapping tool, when I put the mouse near the vertex and before do the left click on the mouse QGIS has crashed, this has happening several times in the last 30 minutes.

I had the same problem, I solved by creating a new profile (settings) and without using third-party plugins.

#2 Updated by Giovanni Manghi over 5 years ago

  • Crashes QGIS or corrupts data changed from No to Yes
  • Priority changed from Normal to High
  • Status changed from Open to Feedback

Please try with a new/clean profile (no 3rd party plugins) and with qgis 3.4.4.

I realized that it was a problem with a plugin that I'm developing. When I generate the feature and save the attributes by the plugin, some cache was still working and the features were duplicated, so when I tried to use the snapping tools it crashes the QGIS.
