[Inkscape-translator] translation not working

Hi,

As of revision 15936 I'm experiencing a quite weird thing: part of translated messages doesn't show up as translated.

On this screenshot you see bottom part of Fill and Stroke dialog.

"_Blend mode" (Режим) and "B_lur" (Размывание) show up as translated (coming from src/ui/widget/filter-effect-chooser.cpp), but names of blend modes (src/filter-enums.cpp) like "Screen" --- don't.

Same thing with names of live path effects. They reside in src/live_effects/effects.cpp and being translated still don't show up as such.

Any idea why? Am I doing something silly?
