           Summary: [GTK] Mismatched free() / delete / delete []
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: louis at mizi.com


I can see the following message when I run GtkLauncher with valgrind(memcheck).
I tested two nightly snapshots. Both of 40102 and 39811 snapshots have same
problem. If you want to reproduce it, just compile webkit with gtk backend and
--enable-debug option, and run GtkLauncher and wait.

I have not tested other port.
