Error in converting PDF to image

[armagan]

I'm getting this error while trying to convert a PDF file to gif:

"Unrecoverable error: undefinedresource in setcolorspace"

..and very long message full of numbers.

I use the following command:

convert -density 200 file.pdf[0] page1.gif

Any ideas what's wrong?

Never mind I solved it. Turns out some other application screwed with Ghostscript. Reinstalling solved the problem.
