[Qgis-user] Crashing with snapping and WFS !?

[Lars I. Nielsen]

Thanks Julien.

It's on Windows. It's at a customer, so I'm not entirely sure what version, except that it's Windows 10.

I did a bug report on it: # 45589.

Cheers
Lars

Hi,


Could you please open an issue here https://github.com/qgis/QGIS/issues
?

Does it happen on Linux or Windows ?

Do you manage to reproduce the issue every time or it happen randomly?

Kind regards,
Julien
