I can reproduce this reliably while browing my Twitter timeline. Unfortunately I cannot seem to isolate the exact tweet that is causing this.

Thread 1 "WebKitWebProces" received signal SIGSEGV, Segmentation fault.

Can you still reproduce this?

[Alberto Garcia]

I haven't seen it in a while with 2.24.3, I guess you can close this and I'll reopen if it happens again.

FTR, I've been able to trigger this fairly often scrolling / resizing the browser in Twitter as well. It's really hard to trigger reliably.

[Carlos Garcia Campos]

Ok, reopening then

[Charlie Turner]

I was getting a reliable reproducer today on Twitter. What seems to have fixed it here is upgrading pixman 0.34->0.38. I also upgrading cairo 1.15.10->1.17.2 and the crashes seem to have stopped.

I don't have time to bisect and find the minimal supported configuration now, but it seems users need newer versions of these packages than was is currently available in Debian/Ubuntu.

This is very old, I'm closing it.
