However Firefox/Thunderbird will still do g_slice_set_config() in main(), it generates the warning, I guess it should be harmless.

G_SLICE=always-malloc will go the job of g_slice_set_config() for Firefox/Thunderbird, to make the program work as expected. This is a different bug, we're tracking this at Bug 833117. In recent gnome update, it makes g_slice_set_config() failed to work for Firefox/Thunderbird. That's why this bug should be marked as "resolved fixed" We got this message before we did "g_quark_from_static_string" in "init", so that g_slice_set_config() won't work in main(). > (process:18754): GLib-CRITICAL **: g_slice_set_config: assertion (In reply to Ginn Chen from comment #18)
