CEF3: error disposing browser instance

[awieser]

Hi,

I receive an error while cleaning up before closing a browser window.
Although most browser instances are successfully disposed I receive the following error message on one.
Since my app is .NET/Mono based, all destructor calls are being made on a seperate GC thread, I guess this is the problem here.
is there anything that can be done ?
The error started to arise after updating CEF to r593 on windows.
