• Status: RESOLVED DUPLICATE

[Sebastian Dröge (slomo)]

Hi,
sometimes webkit/GTK (GIT as of yesterday) crashes when closing or switching a website. Not 100% reproducible but happens quite often.

Backtrace:

Hey, you may want to check https://bugs.webkit.org/show_bug.cgi?id=33746, since you said my original patch fixes many crashes you had =). That replicates the same approach as the original patch's.
