I am running qtcreator on (Kubuntu 16.06, daily)
Package: qtcreator
Version: 3.5.1+dfsg-2ubuntu2
When I open a UI, qtcreator exits with segfault. GBD backtrace is as follows:

I can provide a core dump if desired (25MB), and the sample project. I just don't want the sample project to be wide public.
