View a .xul file (in viewer). Choose File->View Source. It produces the following stack trace. I think "view source" causes something to emit fairly complicated html, which the XUL content sink can't handle. The root cause might be the way "view source" is handled.

bug 3915 is marked verified+fixed so the status whiteboard is no longer up to date.

*** Bug 8081 has been marked as a duplicate of this bug. ***

My hands have deteriorated to the point where I can no longer type. I need help. If you think you can fix this bug on your own, please take it away from me. If you'd like to volunteer to be my hands for a specific bug, then I'll be happy to come up to your cube and sit with you and fix the bug (assuming you have the patience for that).

clearing whiteboard, adding 3915 as a linked dependency. This bug doesn't cause problems in today's opt bits.

resolving as wontfix (in Viewer), use dogfood to view source.

Commercial Mozilla build 1999-10-21-11-M11 displays source code for .xul file without apparent problems. Please reopen if assertion exists in the commercial build. Closing bug.
