           Summary: ubuntu software center hits _XReadEvents() error
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: seb128 at debian.org


The issue has been reported on https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/1211887

The bug and duplicates don't have specific steps to reproduce, that's happening with software-center which is a python-webkit user. The webkit version is 1.10.2 but webkit2 updates seem to have similar issues
