Clicking on help->contents gives: Could not open help directory: Error opening directory '/usr/share/dia/help': No such file or directory
Simply moving the directory doesn't work - error is "Error showing url: There is no default action associated with this location." It's an error message from gnome-open, maybe because I'm running kde. Also the directory is full of .xml files - dia claims that if $BROWSER is set it will use that, I assume gnome-open knows what format these xml files are in and launches an appropriate browser? But for other browsers they need to be converted to html.

The help is installed in /usr/share/doc/dia, but dia and the gnome subsystem apparently expect to find it under /usr/share/gnome/help/dia/ in a locale subdirectory, e.g. /usr/share/gnome/help/dia/en_US or something similar. I expect that dia hasn't had its documentation or ebuild updated in quite a while since locales for internationalization are SOP these days. There's a quick-n-dirty fix. As root, assuming your locale is en_US: cd /usr/share/gnome/help ln -s /usr/share/doc/dia . cd dia ln -s . en_US While this works, the problem really ought to be fixed in the ebuild so as to place the documentation in the proper place without resorting to symlink hacks.
