Comment 19 for bug 367706

Okay, a clean reinstall from the CD fixed all the errors. I then installed the updates, no crash this time, and they all succeeded. The latest Firefox/xulrunner now runs normally. /home is on a separate partition and was not touched by the reinstall, so I should be using the same user-configuration files as before.

In my case I think there must have been some file corruption, although which file would apparently only affect xulrunner, and yet persist across reinstalls of the Mozilla packages, I've no idea. The other possibility is that some in-between updates that were skipped this time somehow affected the update process, which could explain why some other people are seeing the bus error.

Not sure if this info is of any use to anyone, but there you go.
