Odd Dock behavior - cured by restarting the Dock

[wrldwzrd89]

For some odd reason, whenever I install a new application on my Mac, or update an existing one to a newer version, the Dock icon (only in the Applications stack, not on the Dock itself) always shows up as a generic application with a white circle with a line through it over it. Restarting the Dock, logging out and back in, or restarting cures it, until I install the next new app.

Anyone else have this issue?

Never had that in the Dock.

It happens in the application folder with any applications that have been downloaded, as it triggers the "are you sure you want to run this...blah from the internet" dialogue.
