Comment 22 for bug 251617

Can confirm this for Intrepid too.

I noticed that deleting the file localstore.rdf in the .mozilla directory fixed it. For a while, then it came back.
Then I took a look at the file, and saw the lines that was responsible for it. I deleted those lines, and till now I didn't had any problems.

It were the lines looking like this:

  <RDF:Description RDF:about="chrome://browser/content/browser.xul#main-window"
                   height="715"
                   screenX="18"
                   screenY="52"
                   width="995"
                   sizemode="maximized" />

With total wrong numbers (too large).

For the moment I haven't been able to reproduce after deleting lines in that file.
If someone knows who to reproduce it, let me know.
