QGIS crashes on registering a Custom Profile Source with 'Sync Layers to Project' active #65056
Description
What is the bug or the crash?
QGIS crashes when a custom profile source is registered with the "Synchronize Layers to Project" active.
Custom Profile Sources can be registered by plugins, like Swiss Locator.
Steps to reproduce the issue
- Open QGIS (current master, 3.99) and open an Elevation profile widget.
- Check the
Synchronize Layers to Projectoption. - Register a custom profile source. E.g., run the following code snippet:
class MyDummyProfileGenerator(QgsAbstractProfileGenerator):
def __init__(self, request):
QgsAbstractProfileGenerator.__init__(self)
def sourceId(self):
return "my-dummy-profile"
def generateProfile(self, context):
return True
def takeResults(self):
return None
class MyDummyProfileSource(QgsAbstractProfileSource):
def __init__(self):
QgsAbstractProfileSource.__init__(self)
def createProfileGenerator(self, request):
return MyDummyProfileGenerator(request)
def profileSourceName(self):
return "My Dummy Profile"
def profileSourceId(self):
return "my-dummy-profile"
source = MyDummyProfileSource()
QgsApplication.profileSourceRegistry().registerProfileSource(source)The expected result would be this new Elevation profile source in the Elevation layer tree:
