Comment 2 for bug 254223

I have the same issue, I can confirm this happens. It happens to me that the word "won't" gets underlined as an incorrect word with "won" underlined. I am not sure if firefox and other programs such as gedit and pidgin share a common dictionary library - but if they do, that might be the package to attach this bug to. Also see Bug #113511 which needs to be assigned to this package.
