Comment 3 for bug 1010990

Just to also note -
Also can be seen in a non-standard use of the launcher for icons that only launch something. (an Exec= of some scripts or commands.

In that case the the icon normally would pulse or blink for a short period of time during which it can't be re-used. Once it returned to normal , typically 5 sec's, it would then be active again.
Same deal now with those, pulse works fine, with blink the icon remains inactive for the session
