I rather doubt that the gnutls people would be willing to debug on sarge's libraries. I would guess in the next couple of months. Depends on other workload really. If I see the crash again once I'm on etch, I'll update the ticket. Unless there's an obvious error that jumps out at the gnutls devs from the backtrace, I can't see where else to go. Thanks for all your help on this.

Can I mark ist as fixed in 4.63-17, which is the version we released with etch, in the mean time? If you find the bug to happen with etch as well, send found #412886 4.63-17 to [EMAIL PROTECTED], and the bug will be marked correctly. That way, I'll get it out of my bug report list for the time being. Is that acceptable for you? That sounds fine to me. Go for it.
