This doesn't seem to be the fault of icon loading exactly. Both the Svn and
Bazaar plugins start a nested event loop via KJob::exec. This nested loop
apparently processses a timer event which triggers
QQuickWidget::renderSceneGraph. I would guess that all bets are already off
at this point, based on the documentation of KJob::exec.

Sorry I can't look into it any more than that atm, kinda busy these days.
