Comment 1 for bug 744612

Reproduced with Inkscape 0.48+devel r10130 on OS X 10.5.8 (i386)

Alternative steps to reproduce:

1) draw horizontal line
2) add Bend LPE and node-edit the bend path (symmetrically)
3) switch to select tool
4) add gears effect
   -> LPEs are stacked and the first gear is rendered ok
5) reselect Bend LPE and node-edit bend-path
   -> Inkscape hangs
