Oh well, I updated libglade while crossing my fingers. The old one was used by evince, quiver and gizmo (plus other stuff) and all seem to work after updating. Phew!
The +test1 version of abiword installs. Invoked from xterm - it runs.
N810 with 2.2007.50-2 operating system.
I am keeping it on some minutes before starting my tests - no crash.
Now opening my test doc, with graphic letterhead and graphic signature... see what happens...

EDIT: from first tests, it seems that a graphic letterhead plus another graphic in the page is too much for this build. Attempts to move a graph or add some text result in the program to take 100% cpu and stall the tablet, at the point I needed to pull the battery to restart.
I'll make more ordered tests and report on bugzilla as required by Ryan.
