I just did one of those 1000-pending updates on my Fedora 20 installation, and suddenly Firefox is no longer working. It worked fine before. When I run it from console, I see the error: (process:13166): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed This happens both with the installed firefox using yum, as well as when I remove firefox and download the binary from mozilla.com. A search on the internet suggests that the error message was benign and not related to the problem when it popped up in an ubuntu forum a couple of months ago. Does anybody know if this is a common problem? billo -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
