Hi,
I just filed a bug report for POV-Ray export which is broken in 0.47pre4. It appears to have been broken by a move to lib2geom where the path vector includes an extra closing segment even if the path is already closed (see 2geom/path.h). This resulted in extra lines being written out. In addition, there was a problem that existed in 0.46 where paths created by Text->Path may not have their last point exactly on top of the first point (differing sometimes by 0.0002 px). In this case, POV-Ray considers the path open and skips it.
I've attached a patch to the bug report that fixes both problems. I know this is late in the 0.47 release process but as it stands, export to .pov format is useless (POV-Ray fails to process the .pov file due to the extra badly-formatted lines). The patch only effects pov-out.cpp which is used only by POV-Ray export so it shouldn't break anything.
