In addition, I discovered, that changing Desktops does not work as well.
It seems to be the same bug in gnome-shell… As a temporary fix, changing
these two lines in xkb/symbols/de helps:

key <AD03> { [ l, L, bracketleft, Greek_lambda, Up,   Up,   Greek_LAMBDA, NoSymbol ] };
key <AC03> { [ a, A, braceleft,   Greek_alpha,  Down, Down, U2200,        NoSymbol ] };
                                                ^^^^  ^^^^

key <AD03> { [ l, L, bracketleft, Greek_lambda, KP_Up,   KP_Up,   Greek_LAMBDA, NoSymbol ] };
key <AC03> { [ a, A, braceleft,   Greek_alpha,  KP_Down, KP_Down, U2200,        NoSymbol ] };

The same might occur with Left/Right if you have a horizontal Workspace-setup.
