Bug report #18678
System crash/logout with temp layer in Layers panel
|Affected QGIS version:||3.0.0||Regression?:||Yes|
|Operating System:||Mac OS 10.13.3||Easy fix?:||No|
|Pull Request or Patch supplied:||No||Resolution:||fixed/implemented|
|Crashes QGIS or corrupts data:||Yes||Copied to github as #:||26566|
When a temporary memory layer is present in the map legend (Layers panel), hovering the mouse over the temp layer's name will cause unexpected system logout. After logging in and re-starting QGIS, closing and re-opening the Layers panel will allow the temp layer to be selected and deleted.
The temp layer that causes the crash is generated by the Polygon to Lines algorithm; other temp layers (such as those created by Check Validity) do not cause the crash.

Can't reproduce on Linux - may be another OSX specific issue
I believe there are known issues related to High Sierra and WindowServer crashes, which may be at play here. But the crash is tied to a specific action within QGIS (though I couldn't possibly guess why hovering the cursor over a specific type of layer would cause a crash at the system level).
