Debugging problems that involve pumpEventLoop

[rintcius]

Hi,

Usually debugging GWT apps works well, but every now and then I run
into a problem where I don't know how to get to the root of the
problem. These problems involve pumpEventLoop (see below for an
example). Problem here is that the stacktrace doesn't show anything of
my app, so I don't have any clue where to start.
Also the variables don't show anything useful when I debug these kind
of problems.
Is there a way to get more info for this type of problems?

Thanks,
Rintcius
