Unfortunately the backtrace is lacking debug symbols (as always for Arch).
This time, DrKonqi told me he had enough information. Is it a bug in DrKonqi then?
(In reply to ariasuni from comment #2) > This time, DrKonqi told me he had enough information. Is it a bug in DrKonqi > then? No, the fault is with arch to not disable drkonqui.
But DrKonqi is useful in some cases even when there’s no debug symbols, right? Otherwise, I could ask the Arch Linux devs to remove it from a few groups and meta packages, so that it’s not installed by default when installing Plasma.
Sometimes duplicates can be found by just looking at the function names, yes. But for issues that are new, only a backtrace with line numbers helps.

For me the biggest waste of time on this bug tracker are the useless Arch reports. And it's not just my time which is wasted but the users time. They are encouraged to do something for improving the quality and then get the feedback that this all sucks. I think it would be better for everybody involved to not have these bug reports in the first place.
I created a bug report on Arch Linux bug tracker[1] to remove DrKonqi from default plasma software selection, so that in the future there will be less useless bug reports coming from Arch Linux users. [1]: https://bugs.archlinux.org/task/57529
