I get constant crashes on Fedora 21 (pantheon-files is unusable at the moment) when hovering over any icon in the icon view.
The gdb stacktrace is (along with some fatal logs before crashing) :
[_LOG_LEVEL_FATAL 18:04:32.422139] [GdkPixbuf] gdk_pixbuf_get_n_channels: assertion 'GDK_IS_PIXBUF (pixbuf)' failed
