Since last week I can’t run inkscape or firefox anymore. I don’t know what I did to cause this. I only allowed updates to be installed. when I try to run inkscape on the command line I get this error:

 ~> inkscape 
inkscape: symbol lookup error: /usr/lib/ undefined symbol: gdk_pixbuf_get_formats 

I reinstalled gtk, inkscape and firefox but it did not work.
Anyone knows how to solve this.
thanks in advance.

Hello try to install this library
Open your terminal and write

# zypper install

I reinstalled the libgtk-2_0-0 lib but it still doesn’t work.
thank you anyway.
