Dolphin does not display svg icons for directories

[José Abílio Matos]

Hi,
    this is tiny annoyance that appeared sometime (probably more than one 
year).

In dolphin I like to personalize the icons for some directories in my 
home. In one of those directories I use a svg icon and sometime ago (probably 
more than one year) this stopped to work.

The interesting thing is that I use the right button to get the properties 
of the directory the icon shows correctly there.

Is this a bug or a non feature that worked by accident before?

Again this is minor in the sense that there are workarounds but it would 
be nice to be able to use svg.

Regards,
