So now that the slow startup is solved. Back to the error.
Don't think it is so harmless. Nor should exist. It is not there in 2.3.0 and it appears (according to the log) to delay startup a couple seconds. Never satisfied. Those 2 seconds are a big percentage of the 3 second startup.

Back to the error.

I don't know the cause of that error message, so I've written to the developers asking about it. I'll post back when/if I know more.

I don't think that's the case.

One of the developers has replied, saying that he thinks the message probably comes from the operating system when executing a line in ModuleManager::LoadModule

Code: Select all

ModuleMain audacityMain = (ModuleMain) lib->GetSymbol(wxSTRINGIZE_T(MODULE_ENTRY),
                                                            &success);

Where the module manager found a dll that looked like an Audacity module, but was not a valid Audacity module, so stopped trying to load it.
The message would be returned at the time that the module manager decided the "module" could not be loaded, which was at 05:11:56 (the same second that Audacity 2.3.2 started loading). So the time taken by this error is less than a second.

The next logged event is at 05:11:58 when Audacity attempts to load FFmpeg. This occurs after Audacity has scanned the audio system. It is reasonable / normal for that scan to take a couple of seconds. Other initialisation stuff will also be occurring during that 2 second gap.
