I’m glad you are running the program with the -f parameter first, since that is a great way to identify problems.
When you see this type of error (with “QObject”) it usually means something is seriously wrong with the system, often relating to missing prerequisites, libraries, etc. Our program is crashing as a result of these problems, and is mostly likely shutting itself down.
Please review the installation instructions carefully, in particular the prerequisite packages needed, and you will find the problem.
