language files are not imported when installing modules using "features"

I'm having the same problem. drupal_install_module does not take care of the translation by itself (which in my opinion it should), but rather the form_submit of the module form does that by calling

// Notify locale module about module changes, so translations can be
// imported. This might start a batch, and only return to the redirect
// path after that.
module_invoke('locale', 'system_update', $new_modules);

Since Drupal doesn't take care of that automatically, Features has to take care of it by itself. So adding this call to the end of features_install_modules() does this. Note that - by the comment above - anything after that call might never be executed, but as far as I can see, nothing happens afterwards, so this should be fine and it works for me.

Subscribing to this. Looking to use Features for language configuration...though it seems like I can't featurize the available languages themselves yet...

patch #1 worked great for me.
Volx, thanks!

And what about l10n_update module? Currently it doesn't download the translations of the module enabled by the feature. Is a feature problem or should I open a new issue against l10n_update?
