Issue description

I have a particular case where an error in qt.Thread causes ErrorReporting.handle_exception to segfault.

If I replace this

def handle_exception(exc):
    return ErrorReporting.handle_exception(exc)

with this I don't get the segfault (i.e. the exception gets printed and the app keeps running)

def handle_exception(exc):
    traceback.print_exception(*exc)

This is the traceback I got from the core dump:

Steps to reproduce the behavior

I can upload the workflow and the data (~1GB) somewhere if you want a way to reproduce the problem.

The data being send to the dialog in ErrorReporting.handle_exception looks like this (see below). When I create an exception and replace the data with that dictionary, the dialog pops up as expected. So the segfault does not seem to be caused by the data send to the dialog.

data = OrderedDict(
