Suspend to disk -> resume: only locked when invoked from Kickoff

[Diederik de Haas <didi.debian@cknow.org>]

Hello,

When I invoke suspend to disk from Lancelot or the Lock/Logout widget and then resume again, the 
screen is not locked. When I invoke that action from Kickoff it does get locked.
According to Ivan Cukic (author of Lancelot) this should be a configuration or installation problem.
See https://bugs.kde.org/show_bug.cgi?id=206055

1. Does someone else experience this problem?
2. If it is a configuration or installation problem, where to look for the error?
3. If not a configuration or installation problem, is it then a packaging issue? If it is, should it 
be filed in the Debian BTS (since it's a security issue)?

Regards,
  Diederik
