G's Tablet,

You probably don't have some of the dependencies that it requires. My recommended fix is to uninstalling Abiword in the Application Manager.

Then in the Application Manager go to Tools... Application catalog and either add the "Maemo Extra Developer" catalog or enabled it if it's greyed out (Edit... uncheck disabled).
The Catalog details for Maemo Extra Developer (MED for short & is not the same as Maemo Extra Catalog) Catalog are
Web Address: http://repository.maemo.org/extras-devel
Distribution: diablo ; this assumes your running OS2008
Components: free

Once MED catalog is enabled, go back to the main view in application manager and "Browse installable applications". You should be able to install the latest Abiword (2.7.5.0hub1 as of a week ago) from the list that shows up & it will install all the dependencies that are required.

I (and most people on this forum) would recommend you disable the MED catalog after you finish installing Abiword, as you may get presented with updates for other packages installed that may not be ready for mainstream use.

This is how I installed Abiword and it works very well.
