I have added a Bezier line to the outer end of a spiral. (See comment for details.)
After that I selected both, colorized them and gave them a small amount of blur (1.5%).
The problem is, that only the spiral gets blury, but not the Bezier line.
Nevertheless, if I move one node of the Bezier line somewhere else to the outer path of the spiral, select them both and apply a blur, both get blured. I moved the node with the Edit paths by nodes tool and enabled Enable snapping -> Snap notes or handles -> Snap to paths.
Next I can drag one node of the blured Bezier line to the cusp node of the blured spiral by hand and level the line horizontal, by entering the same y-value for the right node that the left node has. Now I can select them both and can change the blur of them simulataneously. By that I can achieve the result that I could not get by the first method. (See EDIT)
I would like to know, how I can blur both objects at the same time without all the effort described above, if this is not a bug.

[EDIT]:
After messing arround with the problem for another while I realised, that the blur of the line only disapears, if I level the two nodes of the line exactly one the same y-values with copy and paste.
In my first try I entered the y-value of the left node of the line in the "y-value box" (at top) of the right line-node by hand, what probably results in not exact the same numbers as copy and paste does.
In my second try to recreate the problem, I copied and pasted the y-value from the left line-node to the right line-node and as soon as I did that the blur of the line disapears.
I could not find any information that this behaviour is intended by the developers. Thus I guess this is a bug and I will report it to them and write about the progress in here.
spiralwith exactly three turns, selected theBezier curve and straight linestool and set its mode toparaxial line mode. After that I enabledEnable snapping->Snap nodes or handles->snap to cusp node(on the right hand side of the window). Now when I hover the cursor over the outer end point of the spiral, the cursor snaps to it and it can draw astraight lineto the right with no interception to thespiral. Can I call that a connection or is that reserved for sth. else? Sorry, that I have not described that better in the first place. – Senkaku May 8 '13 at 10:53
