Danish cartoons were published in Egypt four months ago

As stated before, the twelve "Satanic drawings" were published in Egypt four months ago - without anybody being arrested, or any embassies burned down.

Take a look at this blog and this.

This was during the Ramadan, where people are extra careful not to insult Allah, and yet nothing happened. Four months later the Danish imams would visit with their propaganda booklet and the rest is history.
