Bug#1075761: Desktop icon not displayed

[asciiwolf]

Package: lazarus
Version: 3.0+dfsg1-8

This happens in GNOME, but will probably also happen in other desktop 
environments. The desktop entry of Lazarus (3.0) has empty icon displayed 
instead of the actual Lazarus icon. This is caused by the "Icon=lazarus-3.0" 
entry (icon name). The problem is caused by the dot ("3.0") in the icon name, 
probably because it usually indicates the file type suffix. Everything works 
fine when I rename the icon to "lazarus-30" or "lazarus".
