Although I have the following aspell packages installed on my system:
$ rpm -qa aspell*
I cannot set other document language than English (there is even an “English (Denmark)” (I didn't know they had their own English spelling).
After using gedit for years, this is the first time I find this issue?
(Reporting it upstream, since I'm not sure if the issue happens only with Fedora 13 [but Ubuntu 10.04 also uses gedit-2.30 and I had no problem when setting document language])
Thanks for your help,
Problem solved after installing some enchant dependencies.
Sorry for the noise. Closing the bug as not a bug.
