Strange CSS Bug : 3 Line CSS Code Crashing Dreamweaver CS4

A friend of mine found a strange bug in Dreamweaver CS4. Who would guess that a 3 line CSS code would be able to totally crash Dreamweaver?

Here is the code he tried to write :

@media print{
     #tepe, #rightpanel,
}

While i was trying to replicate this bug, Dreamweaver first crashed at #rightpanel. On my second attempt, i succeeded but was not able to save the file, as Dreamweaver died again. Even saving this simple code in Notepad, and trying to open it with Dreamweaver creates a little disaster.

I just reported this as a bug and waiting for an answer. If I get one, I’ll post it here.

Edit: A mail came after a few hours after my report. Adobe was able to reproduce the bug and it is internally filed. They will look into it.

As suggested, if you encounter this kind of error, be sure to use valid CSS. As this bug appears while writing the code you won’t be able to finish what you started, but however, opening the saved CSS file in another tool and finishing it like this,

@media print{
     #tepe, #rightpanel {}
}

Solves the problem for now.
