Ok, I gave it another try, but not sure whether it improves things much (I 
only get this pretty rarely). Maybe you could try the current SVN trunk, or 
alternatively apply the following patch to rkward/windows/qxembed.cpp in the 
0.4.5 sources:

Index: qxembedcopy.cpp

original QXEmbed
                 if (wstate_withdrawn(window)) {
                     Window parent = 0;
                     get_parent(w, &parent);
                     if (parent == qt_xrootwin()) break;
-                    else if ((i%20) == 0) qDebug ("not really withdrawn, yet 
in loop #%d", i);
+                    else if ((i%500) == 0) qDebug ("not really withdrawn, yet 
in loop #%d", i);
                 }
-                USLEEP(1000);
+                USLEEP(10);
             }
         }

This will be less noisy (hoping to give the window manager a better chance to 
finish its work), and wait longer on systems where usleep is not defined (or 
does not really sleep for the specified number of microseconds, but only 
until the next timeslice becomes available.
