Hi, cannot reproduce here on Linux 2.18.18 (in Affected QGIS version you state 2.18.8.

If I use your url, I get:
server replied: Bad Request url:https://mt1.google.com/vt/lyrs%3Dy%26x%3D%7Bx%7D%26y%3D%7By%7D%26z%3D%7Bz%7D
but not a crash.

If I use: https://mt1.google.com/vt/lyrs=y&x={x}&y={y}&z={z}
It just works.
I do not have Windows 7 here with me.

I can confirm this issue (or a similar one). I'm using QGIS 3.2 on Mac OS 10.13.6 and using the Google Maps satellite layer: http://www.google.cn/maps/[email protected]&gl=cn&x={x}&y={y}&z={z}

I can't exactly predict when the crash will occur, but it seems to be related to specific tiles; i.e., panning/zooming to the same location will tend to trigger the crash repeatedly. It may also be more common with close zoom levels.

I'll attach a crash report from the most recent occurrence.

  • Status changed from Open to Feedback

Nathan - your crash report indicates the crash is coming from Python. Are you using QuickMapServices or OpenLayers?

Please test with QGIS 3.4 - QGIS 2.18 reached it's end of life.

Jürgen, this can be close. Is working as expected in the recent versions.
