When Mozilla is compiled with the following options '--enable-toolkit-gtk2 --enable-default-toolkit=gtk2' makes that GTK2 will interfear with Mozilla in such way that all of Mozillas shift-ctrl key combinations as shift-ctrl-c (mark all news in current newsgroup as read) to not work. Reproducible: Always Steps to Reproduce: 1. Compile Mozilla with '--enable-toolkit-gtk2 --enable-default-toolkit=gtk2' 2. Start mozilla, go to a newsgroup 3. Try shift-ctrl-c Actual Results: Nothing happens Expected Results: The shift-ctrl-c should mark all the unread news as read, but the key combination is blocked by GTK2. As GTK2 uses the shift-ctrl for activating other input methods, which makes that ALL applications that uses any kind of shift-ctrl-<a key> key combinations will never get the "signal", as GTK2 aren't smart enough to let thouse to pass to the application. At the moment there seems to be only one way to get around this problem, and that is to disable the GTK2 toolkit for mozilla, of course a better alternative would be to fix the GTK2 to allow shift-ctrl-<a key> to pass to the application.
Not going to fix this in Gentoo, it's a mozilla/gtk2 problem upstream. Please post the bug there if you want, but they're probably already familiar with the problem, I'd guess. http://bugzilla.mozilla.org/
Yes, bug is known and filed at the bugzilla at mozilla, the problem seems to be knwon by gtk2 team too, and they don't care about breaking applications. My suggestion is that Gentoo don't use gtk2 toolkit in the ebuilds for mozilla, which would be a fix IMHO.
