We have encountered a problem in attempting to create WMS layers using
PyQGIS (QGIS version 3.10.1 - installed from conda-forge).
Attempting to create a QgsRasterLayer with the `wms` provider results in
a segmentation fault.
The following is a reproducible example. Running this code will cause
the segmentation fault. Tested on Ubuntu 18.04.1, python 3.8.2.
import qgis.core as qgc
# Supply path to qgis install location
url = "http://www.glims.org/mapservice?VERSION=1.3.0&STYLES="
print(qgc.QgsRasterLayer(url, 'GLIMS_GLACIERS', 'WMS'))
The only output from running the above code is the following (return
Segmentation fault (core dumped)
Any advice or suggestions would be appreciated. If no one has any
feedback, we will open a bug report.
