Bug #: 29755
           Summary: Deadlock during crash while installing gecko?
           Product: Wine
           Version: 1.4-rc1
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

I did a pure 64 bit build today, and the first time I started an app,
it crashed and hung when the "Wine Gecko Installer" dialog was at about 80%.
I then tried to repeat it, but it didn't happen in two more tries with clean
wineprefixes.

Console output:

wine: Unhandled page fault at address 0x7f1685983730 (thread 0018), starting
debugger...
err:ntdll:RtlpWaitForCriticalSection section 0x100a8
"../../../wine-git/dlls/ntdll/heap.c: main process heap section" wait timed out

This is like bug 28388, but presumably there's no midi involved in installing
gecko.
