Created attachment 473736 [details] trace after the qt update I'm unable to connect anymore with jabber via kopete. I enabled the debug, which I'm attaching to this report. Unless google has changed something at the same time we updated the qt, the update has broke something.
I had to follow this how-to which uses a different authentication mechanism to connect again: https://git.reviewboard.kde.org/r/129239/
Google is changing things all the time, but nevertheless, what files do you have installed in /usr/$(get_libdir)/qt4/plugins ?

Could you please also check the owners of those directories/contents?

I think you should try it with a rebuild of qca (owner of libqca-ossl.so), but any of the other listed plugins could be broken as well.
rebuild qca worked for me
Thanks for reporting, fixed in git commit caebd13188f7462130c2f2d6d825c1ea21a6e229
