I recently rebuilt all of KDE Frameworks and plasma framework master against QT 5.4. I don't know if I am missing something or it is an actual bug, as I use my own scripts to build all the frameworks with the default settings (except I use the prefix /opt)



Reproducible: Always


Actual Results:  
I get this stack trace. I hope it's not too large, as I can't find any place to attach it as a file
