If I start Mozilla using ./mozilla-apprunner.sh and after waiting for it to initialize go to Edit|Preferences, Mozilla always crashes. If I do the same thing under gdb, I get: ... Doing Startup... Looking up BrowserAppCore... Creating BrowserAppCore... BrowserAppCore has been created. Adding BrowserAppCore to AppCoreManager... ...probably for a second time, because the constructor of nsBaseAppCore does this!

THis is not a UI bug, but a code bug and Don''s group is handling this.

I've just tested it on the mozilla/nightly/99-04-20/ build and it worked fine.

Resolved as WORKSFORME. I can't reporduce the problem. Is this still happening for you?

marking verified

Moving from Apprunner to Other component temporarily whilst don and I set proper component. Apprunner component will be retired/deleted shortly.
