Bug Description

Having a path with "knot" effect applied by the Path Effect Editor:
if this path has many crossings (like the picture of a realistic knot)
only one of them can be manipulated by mouse click (first line broken - second line broken - no line broken-...)
there is no obvious tool to switch to other crossings.

Latest try on
Linux 2.6.38-13-generic #52-Ubuntu SMP Tue Nov 8 16:48:07 UTC 2011 i686 i686 i386 GNU/Linux
with inkscape-trunk_1%3a0.48+devel+10782+30~natty1_i386.deb

Works as expected in Inkscape 0.47,
in Inkscape 0.48.0 and later version (including current trunk) the switcher symbol (circle with arrow) for the path effect parameters is missing (new node tool), only the tiny diamond knot is displayed.

Note: if the path effect is applied to an individual path, one can still grab the tiny diamond (on top of the first crossing) and drag it to another crossing. Clicking on it will switch the type of crossing.

Editing the knot path effect for groups no longer works in 0.48.x and trunk.

Update: after the commit in revision 13487, the switcher symbol for the current crossing is visible again (for a Knot path effect applied to a single path, not though with groups - since the initial release of 0.48, the 'Knot' path effect is still broken when applied to a group containing individual paths). As described in comment #2 of related bug #1246550, an update of the switcher symbol is only drawn when the mouse pointer is moved after the change (no immediate feedback when position, size or direction of the switcher symbol has changed).
