Pages and all other iWork 09 apps crashing on startup
Apple – Support – Discussions – Pages and all other iWork 09 apps …. Seems to be a font conflict. Has a great link to a free and legal version of the older software LFE. thanks Peter!
Use Font Book to turn off all but the essential system fonts, then turn them on one by one.
To speed up the font selection you can divide them up into sets and turn the sets on until one triggers the problem. Then divide that set up again until you pin the culprit.
Font Management tools, like Linotype Font Explorer (free) can work some of this out for you.
