Bug#746220: gnome-settings-daemon: Binding ctrl+shift, alt+shift, etc for switching keyboard layout makes shortcuts started with keys not working in any program

Mon Apr 28 12:06:11 UTC 2014

Package: gnome-settings-daemon
Version: 3.4.2+git20121218.7c1322-3+deb7u3
Severity: normal

Dear Maintainer,

Let's assume for clarity that keyboard layout shortcut is set to <Ctrl+Shift>.
In previous versions of GNOME this key combination did not interfere with other
hotkey combinations. But nowadays it is broken.

- Set ctrl+shift as shortcut for switching keyboard layouts
- Try to use ctrl+shift+v, ctrl+shift+c in Terminal -- it doesn't work
(actually Terminal window loses focus when ctrl+shift is pressed, and layout is
switched)

Steps to Reproduce (S); Actual Results (AR); Expected Results (ER)

Test case No. 1:
(S): Open gnome-terminal, type some command, try to copy the command with
<Ctrl+Shift+C> and to paste it with <Ctrl+Shift+V>.
(ER): Text is copied and pasted, keyboard layout is not changed.
(AR): Text is not copied and not pasted, but keyboard layout is changed.

Test case No. 2:
(S): Open Firefox web-browser, open new tab, go to some site, close this tab,
try to recover tab with <Ctrl+Shift+T>
(ER): Recently closed tab is opened, keyboard layout is unchanged
(AR): Firefox opened new tab, keyboard layout is changed

Test case No. 3:
(S): Open any text editor (gedit libreoffice Writer), type some text with
several words, try to select some of that words with <Ctrl+Shift+Left Arrow> or
<Ctrl+Shift+Right Arrow>
(ER): Text is selected by words, keyboard layout is not changed
(AR): Text is not selected, keyboard layout is changed

Test case No. 4:
Open Blender (see
https://bugs.launchpad.net/ubuntu/+source/gnome-settings-
daemon/+bug/1245473/comments/5
for details)

Test case No. 5:
(S): Try to make a screenshot of desired window region with
<Ctrl+Shift+PrintScreen>
(ER): Cursor is changed to cross, desired area is selected by user, screenshot
is copied to clipboard, keyboard layout is not changed
(AR): Whole screen screenshot is saved to clipboard, keyboard layout is changed

The aforementioned test-cases works as expected on previous versions of GNOME
(for example 3.4.2 in Ubuntu 12.04).

Reproducible: Always

This bug exists at least in Ubuntu (see
https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1245473),
RedHat 7 (https://bugzilla.redhat.com/show_bug.cgi?id=1091631), OpenSuSE
(https://bugzilla.novell.com/show_bug.cgi?id=875353), the bug is
reported to upstream (https://bugzilla.gnome.org/show_bug.cgi?id=712667) with
no luck.
