I don't know what's happening there. Can you please install my Qt packages with debugging symbols and see if the output changes? Also, can you please try to get a stacktrace with gdb?

[peet1234]

lucky me, no problem now! didn't do anything.

[The-Compiler]

Weird! No idea what that was, then. Let me know if you see it again!

I'm getting the same error when closing the browser. Which then triggers a fallback so firefox is immediately opened. Any ideas?

@McKean That looks like an unrelated issue, and probably something which has already been fixed - you still seem to be running v1.0.4 which is from November 2017.

[McKean]

oh my... sorry for hijacking this thread. If I still have an issue I'll start a new thread, thanks for the quick reply.
edit: just updated and all is dandy!
