The AbiWord package (in that repository) is the recommended one for N770 devices (hence the mistral designation). I'm an Abi dev and just got an N800, and I recognize that it has some problems, most likely since the ABI/API changed between Mistral and Bora. I plan on getting at least a recompiled version (which should fix most random crashes, I believe) ready within a little while, and hopefully will get AbiWord on N800 whipped into proper shape sometime this summer.
