[Solved] Gnome web (Epiphany) random crashes on certain websites

Hi,

I am sticking to Gnome Web for aesthetic reasons (native app, loads faster and does what I need) except random crashes on certain websites.

Example sites:
1. Page: http://www.akitaonrails.com/2017/01/10/ … istro-ever
2. Go to http://www.omgubuntu.co.uk click on any post, wait until post fully loads:

Error:

Oops!
Something went wrong while displaying this page.

Please reload or visit a different page to continue.

Tried to find reason using gdb, terminal returned:

Help needed:
Any suggestions to fix or drill this down further? And, is anyone else also facing similar problem?

Thanks

Re: [Solved] Gnome web (Epiphany) random crashes on certain websites

Inside gdb you first need to run the application and wait for the crash before trying to read the backtrace. Also you can check if a core dump was created, by typing coredumpctl list in a terminal. If that's the case, then you can view the dump with coredumpctl dump PID.

You can't use gdb on ArchLinux, Arch is missing debug packages :-/ Really an issue for me too.

Re: [Solved] Gnome web (Epiphany) random crashes on certain websites

And for information, I work on another browser for GNOME: https://gnumdk.github.io/eolie-web/

It will segfault too (as it's a webkit bug) but you may like it

@jackpot
Your output suggests that you are not very familiar with gdb. Please see a tutorial on using gdb. You need to run the application before getting the stack trace.
Type "run" and hit Enter before trying to get the trace using "bt full".
Also to get a meaningful trace you application needs to have debugging information in its binary. For that you need to recompile the software using information from: https://wiki.archlinux.org/index.php/St … gdb_output

Re: [Solved] Gnome web (Epiphany) random crashes on certain websites

Thank you for responses, spinnau and adesh for telling me about the need to recompile.  gnumdk for suggesting Eolie (looks good, will try).

Reconsidering the bug being filed upstream, I will watch and wait till it gets fixed.

Re: [Solved] Gnome web (Epiphany) random crashes on certain websites

@ewaller

No, you don't understand how it works... Sure it works with a self compiled software... But if you have a crash in webkitgtk on ArchLinux, your backtrace will be full of undefined symbols (and so unusable).

https://wiki.archlinux.org/index.php/De … ing_Traces

So, one solution, rebuild packages to know where the crash is but for webkitgtk, it means: build glib, gtk and webkitgtk... On my computer, 12 hours to finish compilation.
