I hope my attachment shows the bug clearly (it's a photo from digital camera). I have this problem too but I can't reproduce it every time I launch Evince according described steps. It happens only sometimes. Another workaround is moving icon of application within Launcher to another position. After this (or following move on previous position) the number is shown correctly.
