Package: uucp
Version: 1.07-30
Severity: normal
Dear Maintainer,
* What led up to the situation?
We, for historical reasons (laziness) use UUCP for some inter machine
communications
* What exactly did you do (or not do) that was effective (or
ineffective)?
Installed trixie
* What was the outcome of this action?
>From time to time in.uucpd crashes, apparently in pam_vprompt ()
* What outcome did you expect instead?
No crashes?
It doesn't crash every time, the majority of calls work.
gdb gives me this backtrace:
Core was generated by `/usr/sbin/in.uucpd'.
