GraphMultiEpg and InfoBarGenerics

Hi In 2013 I edited InfoBarGenerics and added such lines 'showGraphEPG': (self.openGraphEPG, _('Graphical Multi EPG')), and def openGraphEPG(self)::

    def __init__(self):
        self.is_now_next = False
        self.dlg_stack = []
        self.bouquetSel = None
        self.eventView = None
        self.epglist = []
        self.defaultEPGType = self.getDefaultEPGtype()
        self.defaultGuideType = self.getDefaultGuidetype()
        self.__event_tracker = ServiceEventTracker(screen=self, eventmap={iPlayableService.evUpdatedEventInfo: self.__evEventInfoChanged})
        self['EPGActions'] = HelpableActionMap(self, 'InfobarEPGActions', {'showEventInfo': (self.showDefaultEPG, _('Show EPG...')),
         'showEventInfoSingleEPG': (self.showSingleEPG, _('Show single service EPG')),
         'showEventInfoMultiEPG': (self.showMultiEPG, _('Show multi channel EPG')),
         'showEventInfoPlugin': (self.showEventInfoPlugins, _('List EPG functions...')),
         'showEventGuidePlugin': (self.showEventGuidePlugins, _('List EPG functions...')),
         'showGraphEPG': (self.openGraphEPG, _('Graphical Multi EPG')),
         'showInfobarOrEpgWhenInfobarAlreadyVisible': self.showEventInfoWhenNotVisible})
        return

	def openGraphEPG(self):
		for p in plugins.getPlugins(where = PluginDescriptor.WHERE_EVENTINFO):
			if p.name == _("Graphical Multi EPG"):
				self.runPlugin(p)
				break

Then I was able to use showGraphEPG in keymap.xml to be run from EPG key. I know that I could change default EPG type from openpli menu and connect GraphMultiEPG to 'showEventInfo'. But I dont want to do this because I like  'showEventInfo' to show default "Description for acutal event". It worked great till yesterday when I performed openpli update. InfoBarGenerics changed, so I added my lines to this new decompyled InfoBarGenerics but it causes greenscreen. Maybe someone would know what is te reason for such situation.
