Note that we also tried the same code with qgis v3.12.0, with the same
result.

Hello,
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
qgc.QgsApplication.setPrefixPath("/path/to/qgis/installation", True)
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
code 139):
Segmentation fault (core dumped)
Any advice or suggestions would be appreciated. If no one has any
feedback, we will open a bug report.
Thanks,
