Konqueror cannot verify certificates

[Michael Schuerig <michael@schuerig.de>]

Starting with a recent upgrade, Konqueror presents me with error 
messages every time I (first) visit a site through https. The message 
is always like this

  The server failed the authenticity check (<site>)
  The certificate cannot be verified for internal reasons

When I look at the details in the "KDE SSL Information" dialog, I can 
discern no problem. In fact, the message at the top states that

  Current connection is secured with SSL.

And further below it says

  Trusted: Yes

I'm running KDE 4.3 and my system is an up-to-date Debian/unstable. 
Does anyone have an idea what might be going wrong here?

Michael
