The
processEvents
call is at the end of a callback method, so it really doesn't do anything (we immediately give control back to Qt after). But it was causing segfaults in the abort acquisition test (which might be another problem?).Also we were getting aborted test runs on our workflows. I think it's because we don't have a proper x environemnt. xvfb gives us that.
