OverflowError: Error while calling Python callback <nav_colorizer> with IDA 7.3

[saidelike]

I had this error with IDA 7.3 when loading any idb, as long as IDArling plugin is in the plugins folder even if I don't use IDArling.

I commented this, which seems to be ok and not creating any issue so in case anyone is annoyed and needs a quick fix.

    def nav_colorizer(self, ea, nbytes):
        """This is the custom nav colorizer used by the painter."""
        self._nbytes = nbytes

        # There is a bug in IDA: with a huge number of segments, all the navbar
        # is colored with the user color. This will be resolved in IDA 7.2.
        cursors = self._plugin.config["cursors"]
        #if cursors["navbar"]:
        #    for user in self._plugin.core.get_users().values():
        #        # Cursor color
        #        if ea - nbytes * 2 <= user["ea"] <= ea + nbytes * 2:
        #            return long(user["color"])
        #        # Cursor borders
        #        if ea - nbytes * 4 <= user["ea"] <= ea + nbytes * 4:
        #            return long(0)
        orig = ida_kernwin.call_nav_colorizer(
            self._ida_nav_colorizer, ea, nbytes
        )
        return long(orig)

There is probably a better way of doing it though.
