Does the bug happen if you start with --temp-basedir?:

yes

Description

After running pacman -Syu on Arch, qutebrowser crashes when I try to do certain things in it. Most notably, opening a tab seems ok, but closing a tab always produces a crash.

[4493:4508:1221/232205.229260:ERROR:broker_posix.cc(40)] Recvmsg error: Connection reset by peer (104)
[1]    4467 segmentation fault (core dumped)  qutebrowser --temp-basedir

If I simply exit qutebrowser, this will be printed:

How to reproduce
I just start qutebrowser, open a second tab, close it, after which it crashes.

No issues here. Could you try to get a stacktrace (without debug symbols for now, my debug packages are quite outdated unfortunately), and also check whether you see the same issue with KDE Falkon (falkon in the repos)?

Yeah, falkon crashes too (open a tab, close it):

That reveals that the crash is deep inside your graphics driver - nothing qutebrowser can do about it. If you have the (discouraged) xf86-video-intel package installed, you might want to try uninstalling it, in order to use the modesetting driver instead.

Uninstalling it didn't help, but thanks for looking into it nonetheless.

I'm assuming you did reboot (or at least restart X11) after doing so?

@jumpscare

Author

Yes, I did pacman -Rs x86-video-intel x86-video-vesa and rebooted. I supposed my next stop will be the arch linux forum. Will report back here once I find a solution.
