currently #23 in the non-hang non-flash crash list in reports for 2010 05 06. we should keep an eye on this as user ramp up.

this has fallen off. only one crash yesterday.

In trunk builds, there is a spike in crashes from 4.0b8pre/20101110 build. It is now #38 top crasher in 4.0b8pre for the last 3 days. Stack trace looks like: Frame Module Signature [Expand] Source 0 xul.dll base::BaseTimer_Helper::OrphanDelayedTask ipc/chromium/src/base/timer.cc:13 1 xul.dll mozilla::plugins::BrowserStreamChild::Deliver dom/plugins/BrowserStreamChild.cpp:235 2 xul.dll mozilla::plugins::PluginInstanceChild::AnswerNPP_Destroy dom/plugins/PluginInstanceChild.cpp:2961 3 xul.dll mozilla::plugins::PPluginInstanceChild::OnCallReceived obj-firefox/ipc/ipdl/PPluginInstanceChild.cpp:1681 4 xul.dll mozilla::plugins::PPluginModuleChild::OnCallReceived obj-firefox/ipc/ipdl/PPluginModuleChild.cpp:574 5 xul.dll mozilla::ipc::RPCChannel::DispatchIncall ipc/glue/RPCChannel.cpp:517 6 xul.dll mozilla::ipc::RPCChannel::Incall ipc/glue/RPCChannel.cpp:503 7 xul.dll mozilla::ipc::RPCChannel::OnMaybeDequeueOne ipc/glue/RPCChannel.cpp:434 .. The regression range for the spike is: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=df1d1ff6b489&tochange=0f17e5f1eb01 It is probably a consequence of bug 611593 who is going to be fixed in 4.0b8pre/20101116 build.

Some user reported a crash, and this bug is listed in the related bugs section: https://crash-stats.mozilla.com/report/index/bp-d8bd506f-d2c0-4d5d-ba49-f26c72110407 0 xul.dll base::BaseTimer_Helper::OrphanDelayedTask ipc/chromium/src/base/timer.cc:13 1 xul.dll mozilla::plugins::BrowserStreamChild::Deliver dom/plugins/BrowserStreamChild.cpp:235 2 xul.dll MessageLoop::RunTask ipc/chromium/src/base/message_loop.cc:340 3 xul.dll MessageLoop::DeferOrRunPendingTask ipc/chromium/src/base/message_loop.cc:348 4 xul.dll MessageLoop::DoWork ipc/chromium/src/base/message_loop.cc:448 5 xul.dll base::MessagePumpForUI::DoRunLoop ipc/chromium/src/base/message_pump_win.cc:213 6 xul.dll base::MessagePumpWin::RunWithDispatcher ipc/chromium/src/base/message_pump_win.cc:52 7 xul.dll base::MessagePumpWin::Run ipc/chromium/src/base/message_pump_win.h:78 8 xul.dll MessageLoop::RunInternal ipc/chromium/src/base/message_loop.cc:216 9 xul.dll MessageLoop::RunHandler 10 xul.dll MessageLoop::Run ipc/chromium/src/base/message_loop.cc:173 11 xul.dll base::Thread::ThreadMain ipc/chromium/src/base/thread.cc:165 12 xul.dll `anonymous namespace'::ThreadFunc ipc/chromium/src/base/platform_thread_win.cc:26 13 kernel32.dll BaseThreadInitThunk 14 ntdll.dll __RtlUserThreadStart 15 ntdll.dll _RtlUserThreadStart He says it happens when using the Download Helper extension to save a file. He's using 3.6.16, though.

He's using Download Helper 4.8.6, if that helps.

I can't reproduce this in automation with Beta/11, Aurora/12, or Nightly/13 and current versions of Flash. Looking at crash-stats this is a 3.6-4.0 crash. Many people have older versions of Flash though at least one I saw was current. This has been on file since 2010 and not fixed and with 3.6 near EOL I'm going to WFM it.
