I just don't happen to know the English name for the feature. The bug is that I coudn't find any way to _disable_ the feature.
Steps to Reproduce:
1. Run pan
2. Try to post a article
3. Write some text in Finnish (or any other language than English)
95% of the words I had written were underlined and red.
The software should have given me an easy way to disable... spell-checking? Is
that what it is called? :)
I will post "emerge info" later if someone asks for it. I really think that
it's not relevant in this case.
Well, pan uses gtkspell. Assuming you've setup gtkspell to use a Finnish dictonary Pan will not flag finnish words as misspellings.
Alternatively you can disable support for gtkspell. Add -spell to your use flags when when you emerge pan.
On one hand, the comments made by Geoffrey are correct; you might want to spend a few minutes trying to figure out the way to make GtkSpell work with your favorite dictionary (setting the LANG environment variable seems to do the trick for me).
However, I think this is a valid issue after all, just not a Gentoo-specific one. GtkSpell's additions to the GtkTextView widget UI are very scarce, and there is no direct way to change your dictionaries or disable spelling through the right-click menu. Most of GtkSpell's functionality is provided only at the API level, so it is a matter of the Pan developers if they want to provide "an easy way to disable spell-checking", as you put it. :)
Closing as UPSTREAM for now. Please let me know if you have something else to add to this.
