"The crash belongs to a package that is not installed." ???

[Gabor Toth]

Just a question here.

>From time to time I get a system crash window popping up and saying that there was a crash.  I click on send the report - of course - and then it comes up with another window saying "The crash belongs to a package that is not installed."

I do not get it.  How can a package crash that is not even installed? 
Can anyone light my way in this?

Thanks.
