Hi Chris, The problem is wxPython is using a dynamic library which is installed on your system, but which is of a version that is not what wxPython expects. Unfortunately I don't know anything about ArchLinux. And after a bit of googling, I suspect that this problem may not have anything to do with wxPython - it looks like an incompatibility in a lower level library that has started occurring only in the past couple of weeks: https://bugs.archlinux.org/task/57869 https://forums.opensuse.org/showthread.php/530262-Error-applications-using-libpango-(gimp-chromium-firefox-etc-) https://bugs.archlinux.org/task/57976 The links above all suggest that updating your version of glib2 may solve the issue.
