Hi guys, my first post here: I'm facing a strange problem while developing my first video addon for Kodi v19 Matrix. I'm testing my code in two different environments:

1. A fresh install of Kodi v19.4 Matrix on a Windows 10 x64 desktop with Python 3.10.6 (these are the first lines of kodi.log when Kodi starts):

2. LibreELEC 10.0.3 on a Raspberry Pi 3 (starting of kodi.log here):

My problem is that Kodi crashes and restarts with a SIGSEGV on my RPi 3 (on Windows everything works fine) when I call "self.close()" on a WindowXMLDialog to close it, but only if I override its "onInit" method. To clarify, here's a minimum addon i've created that reproduces the issue:

txt:


\root

  \resources

    \lib

      ui.py

    \skins

      \Default

        \1080i

          search_page.xml

  addon.xml

  icon.png

  main.py

Addon.xml code

xml:


<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<addon id="plugin.video.elendar.crash_test" name="Crash Test for LibreELEC 10.0.3" version="1.0.0" provider-name="Galaron">

  <requires>

    <import addon="xbmc.python" version="3.0.0"/>

    <import addon="script.module.beautifulsoup4"/>

    <import addon="script.module.requests"/>

  </requires>

  <extension point="xbmc.python.pluginsource" library="main.py">

    <provides>video</provides>

  </extension>

  <extension point="xbmc.addon.metadata">

    <language>en</language>

    <platform>all</platform>

    <assets>

      <icon>icon.png</icon>

    </assets>

  </extension>

</addon>

main.py

python:


import xbmcaddon



from resources.lib.ui import SearchPage

from resources.lib.utils import KodiUtils



# Get addon instance

_ADDON: xbmcaddon.Addon = xbmcaddon.Addon()

# Get addon full path

_ADDON_PATH: str = _ADDON.getAddonInfo('path')



if __name__ == '__main__':

    KodiUtils.log("Showing search page")

    search_page: SearchPage = SearchPage('search_page.xml', _ADDON_PATH, defaultRes='1080i')

    search_page.doModal()

    del search_page

    KodiUtils.log("Search page closed") # I can see this message in logs, so controls returns here when dialog closes, but then Kodi crash

ui.py

python:


import xbmcgui

from xbmcgui import Action



from resources.lib.utils import KodiUtils



class SearchPage(xbmcgui.WindowXMLDialog):

  __SEARCH_BAR_ID: int = 9001

  

  # IF I COMMENT THESE TWO LINES, CODE WORKS ALSO ON RPi 3

  def onInit(self) -> None:

    self._search_bar = self.getControl(SearchPage.__SEARCH_BAR_ID)



  def onAction(self, action: Action) -> None:

    KodiUtils.log("User has requested action with ID {}".format(action.getId()))

    if action.getId() in [xbmcgui.ACTION_BACKSPACE, xbmcgui.ACTION_NAV_BACK, xbmcgui.ACTION_PREVIOUS_MENU]:

      KodiUtils.log("Closing by calling self.close()")

      self.close()

    else:

      super().onAction(action)

This is the kodi.old.log and this is the kodi_crash.log 

Sorry if I've some dumb/noob mistake, but I've read a lot of examples and it seems all correct to me. Thanks you all for the support in advance!
