libqgpgme7:amd64 (1.10.0-1ubuntu1, 1.10.0-1ubuntu2)
when I lock my screen with Ctrl-Alt-L I get the lock screen background image and nothing more.
I am unable to unlock the GUI.
I can go to a different virtual terminal with Ctrl+Alt+F2, but to get back to the GUI I need to reboot the host.
I have a dual monitor setup with one monitor rotated at 90 degrees.
When I disconnect the rotated screen, I do get to see the password field and the unlock button, but I can't interact not with the keyboard nor with the mouse, and I am forced to reboot then too.
As a work around I disabled the automatic locking of the screen, but this is not a secure solution.

I was able to reproduce this behavior with running manually /usr/lib/ x86_64- linux-gnu/ libexec/ kscreenlocker_ greet
Oddly enough the first time I ran it I did got the password prompt and was able to unlock it and return to my desktop.
Running it again reproduced the reported issue, i.e. no password widget and thus no way to unlock it.
Killing kscreenlocker_greet from an other VT, didn't fix the issue, rather background became black, and only the mouse pointer was moving around.
