Hello,
When ksshaskpass is spawned by program running during early KDE startup
it is impossible to type the password.

During startup I can see first kwallet window, it even got focus (slightly blue
frame round the text input field), but no keystrokes are registered. I have to cancel and then It appears ksshaskpass window, and occur the same.

No black dots are visible during typing the password. No key is added
to ssh-agent. The ksshaskpass window, however, can react to <Enter> key.

Kind regards,
Juan
