[Bug-gnuzilla] Icecat bug

[Pau]

Hi,

I have installed Icecat on my computer following the two ways explained 
here: https://wiki.ubuntu.com/IceCat and in both cases I can run and use 
the program, but I can't add it to the dock or put an icon on my 
desktop. When I run it I get the warnings and errors I attach, but I am 
not sure about changing the source code because it may be a bad 
configuration of my device instead of a bug. Any help is welcome, thanks!
