Hi Sebastien, I will try and get the backtrace. Have not done that before as I am new to linux world. Steps to reproduce are easy - just run evolution from terminal and access the attachments in an email and you will see errors similar to mine in terminal. This is also dependent on the theme which is selected in ubuntu apperance prefs. Here is the errors with human theme and then with the clear looks theme - the draw_box errors. ** (evolution:11239): CRITICAL **: murrine_style_draw_box: assertion `width >= -1' failed **
