[solved] Where do I start when an application crashes?

I use dwb as browser, but after a new archlinux installation is keeps crashing. So I was wondering how and where I can find info on my system that can help me figuring out why an application crashed?

Start it from the terminal so you get some info when it freezes / crashes.
Which version of dwb are you using, the one from the official repos? If so, try dwb-git from the AUR.

Yes, I already tried that but it just returns to the prompt after a crash.

I'm using dwb from the official repos. I'll switch to dwb-git from AUR.
Although a crashing dwb was the reason for this topic, my question was meant as a general one: what are the first things you should do in case of a crash of any application.

Run it with strace or gdb, see if there's any useful information about what's going wrong.

Check the logs and systemd's journal.

With regard to strace and gdb, see https://wiki.archlinux.org/index.php/St … ging_Guide & https://wiki.archlinux.org/index.php/De … ing_Traces

Thanks for the suggestions.
And karol, thank you for the links. That was what I was looking for. At first glance it looks a bit daunting for my modest archlinux capabilities. But it is a place to start with very small steps!
