Still valid wine-staging 1.9.14

Something wrong here?

394 NTSTATUS WINAPI RtlDeleteCriticalSection( RTL_CRITICAL_SECTION *crit )
 395 {
 396     crit->LockCount      = -1;
 397     crit->RecursionCount = 0;
 398     crit->OwningThread   = 0;
 399     if (crit->DebugInfo)
 400     {
 401         /* only free the ones we made in here */
 402         if (!crit->DebugInfo->Spare[0])
 403         {
 404             RtlFreeHeap( GetProcessHeap(), 0, crit->DebugInfo );
 405             crit->DebugInfo = NULL;
 406         }
 407         close_semaphore( crit );

Still crashes, but the crash could be somehow related to

fixme:msg:unpack_message msg 7f (WM_GETICON) not supported yet

wine 2.0rc3 and staging same version.

--- Comment #7 from Damjan Jovanovic  ---
The only call to DeleteCriticalSection in the app's source is in file
tcl/win/tclWinNotify.c:

void
Tcl_FinalizeNotifier(clientData)
    ClientData clientData;      /* Pointer to notifier data. */
{
    ThreadSpecificData *tsdPtr = (ThreadSpecificData *) clientData;

DeleteCriticalSection(&tsdPtr->crit);
    CloseHandle(tsdPtr->event);

The backtrace contained:
Unhandled exception: page fault on read access to 0x00000000 in 32-bit code
(0x7bc35a61).

which probably means NULL was passed to DeleteCriticalSection(), ie.
ThreadSpecificData.crit is NULL. But why is it NULL?
