FR: missing gnome2_icon_cache_update()

[jonasstein]

Many packages use icons, but do not call gnome2_icon_cache_update()

I do not know which script does find this at the moment.
Some ideas:
one could grep for icon (does not work well picard does not use "icon" for example), or look up which files are installed on http://portagefilelist.de/
http://files.portagefilelist.de/sqldump/

this database can be a good tool for many tests.

there are also ehelper functions doicon and newicon, but some packages copy the files in a creative manner.
Probably the best to start with a non perfect solution and improve later.

This is how the problem is displayed after installation
