Bug report #12245
iface.mapCanvas().refreshMap() segfaults QGIS
|Affected QGIS version:||master||Regression?:||No|
|Operating System:||Easy fix?:||No|
|Pull Request or Patch supplied:||No||Resolution:||invalid|
|Crashes QGIS or corrupts data:||Yes||Copied to github as #:||20430|
Needed to refresh my mapcanvas for a plugin, and refresh() did not do the job, so I found refreshMap()...
That just crashes QGIS here, running master on Debian.
I see it is a private slot, and tried other slots.
Not sure if this can be handled more gently, or it is just a fact of life: you should not call private slots in pyqgis....

- Resolution set to invalid
- Status changed from Open to Closed
refreshMap() is private because it is not meant to be used from outside... It deliberately crashes on an assertion condition. It is not a part of API, the fact you can call it is just something resulting from PyQt's new signals/slots mechanism.
