Bug ID: 190787
Summary: [GTK] Crash while doing drag and drop
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: WebKit Gtk
Assignee: webkit-unassigned at lists.webkit.org
Reporter: tpopela at redhat.com
CC: bugs-noreply at webkitgtk.org
Reported in downstream in 2.22.0 - https://bugzilla.redhat.com/show_bug.cgi?id=1641396. But what's even more interesting is that the same crash was reported in past against 2.6 as well in https://bugzilla.redhat.com/show_bug.cgi?id=1166599
