Hi, this version has this error when you try to click in the refresh button to search for new plugins (Nothing happens). This issue has been fixed on version 2.4.2-2 almost a month ago.

Carla logs:

Traceback (most recent call last): File "/usr/share/carla/", line 1692, in slot_refreshPlugins if PluginRefreshW(self,, self.fUseSystemIcons, self.hasLoadedLv2Plugins).exec_(): File "/usr/share/carla/", line 1230, in init self.fThread.pluginLook.connect(self.slot_handlePluginLook) TypeError: decorated slot has no signature compatible with SearchPluginsThread.pluginLook[float, str]
