Will need more debugging details here - it's not an issue on most installs

I am on Arch 64bit. Last terminal entries were:

Warning: Empty filename passed to function
Warning 4: Failed to open /opt/qgis-git/share/qgis/resources/data/world_map.shp, Permission denied.
Warning 4: Failed to open /opt/qgis-git/share/qgis/resources/data/world_map.shp, Permission denied.
Warning 4: Failed to open /opt/qgis-git/share/qgis/resources/data/world_map.shp, Permission denied.

It is worth mentioning, that I did not import a shapefile named "world_map.shp".

QGIS3 (compilation date 20180121) crashes when trying to open the layer properties of other vector-based layers such as geopackages as well. Hope that helps and thanks

What is the build revision number (in the about QGIS window, or the main window title)?

That's used for the CRS selection dialog. Does it exists and is it readable at the given location?

Thanks for your reply, I guess these lines popped up before the crash happens. the aforementioned shapefile is located under the specified location and can be visualized in QGIS. Once trying to open the correpsonding layer properties, QGIS freezes.

My build number is 9451f2e412

#17943 and #17936 have some backtraces on similar (likely same culprit) crashes.

The world_map.shp warning should be completely unrelated.

I'm also building with qt 5.10.
A full backtrace. Hope it helps.

I can confirm on macos, the workaround proposed here https://github.com/qgis/QGIS/pull/6301 fixes the issues either the crash with options dialog that the hangs in the vector properties.

Could not replicate, moment when it crashed is foggy (some hours ago). It was in close "temporal relation" to adding a vector layer or zooming/panning around in it so it might fit here.
