Status changed to 'Confirmed' because the bug affects multiple users.

Seems like a new version of the qt4 libs has been published today. Now libqtcore4 (and also Skype) installation is working for me again.

I can confirm, after just downloading and installing the latest batch of patches there are no more dependency issues and Skype works fine.
