Comment 6 for bug 276118

OK. The installer is doing nothing unusual here. What's happening is that the "enchant" spell-checking library has a number of spell-checking providers that are each supposed to provide an interface that lists the available dictionaries. Most of them check which dictionaries are available and return those.

However, the "zemberek" provider, which supports Turkish, doesn't check which dictionaries are available; it just unconditionally offers Turkish, without checking whether the zemberek server is available. We don't seem to package the zemberek server for Ubuntu at the moment, although it is free software and potentially could be packaged (http://code.google.com/p/zemberek/), so at the moment we'll always be wrong in claiming to offer spell-checking using it.
