Subject: Specify a fallback icon to QIcon::fromTheme()
X-Git-Url: http://quickgit.kde.org/?p=dolphin.git&a=commitdiff&h=44d4d2ea715719a08c639541530a5b330647297d

Specify a fallback icon to QIcon::fromTheme()

The default fallback of QIcon::fromTheme() is QIcon(), i.e. a null icon.
Set the generic "unknown" icon as fallback to prevent missing icons for
filetypes that specify an icon name that doesn't exist.

This also gets rid of "QPixmap::scaled: Pixmap is a null pixmap"
warnings in that case.
