Bug#416506: Unlock dialog does not appear

Package: gnome-screensaver
Version: 2.18.0-1
Severity: grave

Hi,

After I lock my screen with gnome-screensaver from experimental, I am
then unable to unlock it.

When I press some key or move the mouse, instead of showing the unlock
dialog, It briefly shows the mouse pointer and nothiing happens. The
only way out is to switch to the console and kill gnome-screensaver.

There are no messages in ~/.xsession-errors. I use the "Blank screen"
screensaver.

When I start it with "gnome-screensaver --no-daemon --debug 2>g-ss.log"
and then activate/kill, I get the following on the terminal:

I've tried to search through upstream's bugzilla and did not find an
exact match. 392072 looks similar, but I am not certain if it is the
same - I get no password dialog at all.

Another thing. While browsing through the bugs, I've discovered that a
long-standing problem is fixed - displaying some sort of keyboard
switcher in the password dialog was added. I am unable to add the
keyboard switcher applet to the panel - it hangs untill killed. This may
have something in common with the problem I have. The keyboard layout is
not quite standard:

Section "InputDevice"
    Identifier      "Generic Keyboard"
    Driver          "kbd"
    Option          "CoreKeyboard"
    Option          "XkbRules"      "xorg"
    Option          "XkbModel"      "pc104"
    Option          "XkbLayout"     "bg,bg"
    Option          "XkbVariant"    "latin,phonetic_bds"
    Option          "XkbOptions"    "grp:alt_shift_toggle,grp_led:scroll,altwin:meta_win,lv3:rwin_switch"
EndSection


Thanks,
