QGIS » QGIS Application

Attaching a log of an attempt with latest nightly (nothing new, just the addresses and times change but I realized the version number in the file I had attached is incomplete).

Versions of packages qgis depends on:

Anything I can do to investigate this?

Thanks.

Same error on 3.0.2.

Attaching a log.

Anything useful I could try?

Thanks.

New backtrace with 3.0.3.

Any clue how to debug this? Anything more I should provide?

The problem was due to another version of PyQt5 being installed locally.

I realized today by accident that `from PyQt5 import QtCore` would segfault.

I purged my local pip3 installations of pyqt5 and sip to only keep the one installed by the package manager and QGis starts as expected.

I'm not sure exactly what was wrong, but I don't think it is QGis's responsability.

Sorry about the noise. Hopefully, this bugreport will help someone with a similar issue (hint: try to import QtCore in a Python interpreter).
