It was, I tried the old patch again but updated kdeui and kfile and got the 
same result. With the new patch you posted this morning it's fine though.

They're all serving a given purpose which is the capacity bar fading. So 
really I'd say that:
+    void insertTimeLineMap(const QModelIndex &index, QTimeLine *timeLine);
+    void removeTimeLineMap(const QModelIndex &index);
+    QModelIndex indexForTimeLine(QTimeLine *timeLine) const;
+    QTimeLine *timeLineForIndex(const QModelIndex &index) const;
Should be:
+    void addFadeAnimation(const QModelIndex &index, QTimeLine *timeLine);
+    void removeFadeAnimation(const QModelIndex &index);
+    QModelIndex indexForFadeAnimation(QTimeLine *timeLine) const;
+    QTimeLine *fadeAnimationForIndex(const QModelIndex &index) const;

_k_triggerDevicePolling()? (AFAIK it doesn't really poll, just does the 
necessary so that the device polling will happen "soon enough")

Please consider the proposed renames first. Other than that it seems ok to 
commit (although keep in mind that because of the patch size I might have 
overlooked some potential issues).
