When trying to run "unison" with the gui Ive suddenly started getting this in syslog - just get "Segmentation Fault" at the commandline. Unison works in text mode ok. System was recently upgraded to gnome 2.26, and pixman-0.16.2, and I am sure that unison has worked since the upgrades. Rebuilt pixman and a few other things with no luck so far ...
