Now, aptitude could tell you why it has been installed:

So, on this system of mine it has been installed as a recommends. Probably with the initial installation because I usually switch off recommends. I probably could also remove it without further damage but I'm not sure. Didn't RTFM.
You can safely remove gtk3-tqt-engine-trinity and that at-something-funny-thingy will be gone, too. Does gtk3-tqt-engine-trinity actually work?

I keep it having around as an old habit but indeed run into problems every now and then. I don't remember the specifics but it is probably the cause for Bill's "browser not starting" problem. See the other thread about it.
