plugin crshes when i use Preference / Options

[MicZev]

Hello,
I'm using QGIS 3.4.4 with Windows.
Versions : matplotlib 3.0.0, numpy 1.15.4, Pyhton 3.7.0

When the plugin is active and I go to Preferences / Options and then validate options, Qgis crashes with 2 messages :

• RuntimeError: wrapped C/C++ object of type ContourGenratorAlgorithm has been deleted
  File "C:\Program Files\Qgis 3.4\profiles\default\python/plugins\contour\ContourGenratorProvider.py", line 55, in loadAlgorithms
  self.addAlgorythm( alg)
• Qgis Crashed

Thanks

HI @MicZev Thanks for reporting this. I'll have a look at this over the next few days. This looks a bit obscure (in the magic that happens between C++ and Python) so it may take a while to track down.

@MicZev Just also to confirm that I can reproduce the error (on linux

Hi.
I'm having almost the same issue with QGIS 3.12 bucuresti.
When the plugin is active and I go to Preferences / Options and then validate options,
Qgis show the error messages : RuntimeError: wrapped C/C++ object of type ContourGeneratorAlgorithm has been deleted.
QGIS doesn't crash,and i can work with the plugin,
but still - what may be the issue and how can i resolve it?
thanks,
Aridzv.
