Rapache crashes and cannot restart if favicon is 0 bytes

[David Gurba]

Rapache has been working great (I've commented on the blog before that its working in 12.04). I'm not 100% sure I'm running the latest code. But, I was debugging a site and got annoyed with log messages about a missing favicon from Apache.

So I just did `touch favicon.ico` so Apache would stop complaining, it does.

Rapache though appears to not like this because its trying to load a favicon that doesnt exist and crashes. At the CLI I get:
reloading vhosts..
Traceback (most recent call last):
  File "/home/dgurba/apps/rapache/RapacheGtk/VirtualHostGui.py", line 525, in on_button_save_clicked
    self.parent.refresh_vhosts()
  File "/home/dgurba/apps/rapache/RapacheGtk/RapacheGui.py", line 381, in refresh_vhosts
    self.vhosts_treeview.load()
  File "/home/dgurba/apps/rapache/RapacheGtk/VhostsTreeView.py", line 73, in load
    pixbuf = gtk.gdk.pixbuf_new_from_file( favicon )
glib.GError: Image file '/var/www/2013/debug/projects/eap-live-01042013/www/favicon.ico' contains no data
Errors status: -1

And the GUI paints the vhost list upto the alphabetical ordinal of the vhost in question, then stops painting the table list.

I was able to fix it on my end by just getting a valid favicon file -- but my "sysadmin" hack of an empty favicon shouldnt hose Rapache.

I use Rapache daily as my lean MAMP Dashboard or OSX VirtualHostX linux admin UI. It's great, thanks for all the work.
