Description

We are using a QGIS-project with several WMS-Layers(up to 20) and Shapefiles for digitizing. There are random freezes of QGIS which end up in a crash of the program.
Minidumps are not always written but sometimes.
I tried to analyze the Dumpfiles with WinDBG but have no experience in debugging QGIS-dumpfiles so I am not sure if I need more QT-symbol-files to analyze the dumpfiles properly.
I have attached a textfile with some information from the dump-analyze:
Here a part of the attached file:

perhaps is has something to do with the snapping-tools?
