Comment 0 for bug 1171434

Current trunk no longer sets parameters based on <optiongroup> defined in the INX file.

This INX element is still used by a couple of extensions bundled with Inkscape, as well as by an unknown number of externally developed custom extensions.

Sample steps to reproduce:
1) launch trunk with default (new) prefs
2) open 'Extensions > Render > 3D Polyhedron'
3) switch to the second tab, define different rotation angles for X-, Y-, and Z-Axis
4) preview the result

Expected result:
The inserted cube is rotated around each axis as defined the in the dialog

Actual result:
The inserted cube is rotated several times around the default axis (X). It is not possible to rotate it around an explicitly chosen different axis (Y, or Z).
The parameters for the <optiongroup> are also no longer stored in the preferences file.

Not reproduced with Inkscape 0.48.4 and 0.48+devel <= r12265
Reproduced with Inkscape 0.48+devel r12268 and later revisions

Possibly introduced with r12267 "fix bug where extension radiobutton parameters cannot be set from cmdline"

- GTK+/X11 2.24.13, gtkmm 2.24.2, glib 2.32.4, glibmm 2.34.1

Note: does not affect lists of choices defined with <enum>
