           Summary: [Qt] crash in debug mode just before exit
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit Qt
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kb at inf.u-szeged.hu


My test case was the following: starting QtLauncher (a debug build), navigating
to wave.google.com, sign in, wait for a little but do not wait until it could
load, and close the window (it can be necessary because in that case there are
living timers that has not been fired). Unfortunately, it is not easily
reproducible. Actually, I started QtLauncher inside gdb, but I cannot say it is
always reproducible even with gdb. If I remember correctly I also saw this
problem inside valgrind before (what made me angry since valgrind is unusable
for leak hunting when the application do not exits normally).
>From the backtrace I realized that isMainThread() is called during the
destruction of the QCoreApplication inside an ASSERT.
In that case it crashes since it tries to get the thread id of the
QCoreApplication (not the ASSERT crashed but the execution of it).
