Bug#429422: gnome-screensaver: Screensaver blanks screen without ability to restore

[Brian Sipos]

Package: gnome-screensaver
Version: 2.18.2-1
Severity: important

When the screensaver is fading out, a mouse movement will cause the 
screensaver to be disabled. Once the fade-out has occurred, a mouse 
movement will promopt for a password to restore display.
If a mouse movement occurs at some time when the screen has completely 
darkened from the fading for some reason the password prompt will never 
display and it is impossible to restore the display without killing the 
X server and logging-in again. This is a very severe problem and I have 
experienced this issue several times now.
I can attempt to repeat the issue, but so far it has occurred at 
inopportune times and is very annoying.
