+author: Szymon Tomasz Stefanek <s.stefanek@gmail.com>
+
+This patch fixes a crash deep inside the qt painting engine.
+
+The toplevel shared painter is instantiated by the topmost window
+which "owns" the backingstore buffer. The topmost window then recursively
+asks the children to paint themselves with the shared painter.
+With certain widget hierarchies it turns out that the topmost window
+may be asked to paint itself deep inside the recursive painting stack:
+a sort of "hierarchy-looping recursion".
+The window will do the job and then happily destroy the shared
+painter leaving the outer stack frames with a dangling pointer.
+
+This patch stops the "looping recursion" when it's triggered
+with a shared painter already active. The bug doesn't seem to
+be present in qt 4.5 snapshots, but in the meantime we need this fix.
