The slider range issue could be overcome by this:
--- libs/widgets/imageplugins/imageregionwidget.cpp     (revision 750612)
+++ libs/widgets/imageplugins/imageregionwidget.cpp     (working copy)
 @ -118,6 +118,10  @
     double dstWidth  = contentsRect().width();
     double dstHeight = contentsRect().height();
     double zoom      = QMAX(dstWidth/srcWidth, dstHeight/srcHeight);
+    // For small images we start with 100% zoom, i.e. smaller than contentsRect.
+    if (zoom>1.0)
+        zoom = 1.0;



But this (of course) addresses non of the problems one gets.

Gilles, I think Markus suggestion #c13 to apply your patch 
is a good one: for normal images everything is ok (and that is really the majority I would guess), while for small images we have
to find the origin of the problem (seems not an easy one at first glance).
