Package: cups
Version: 1.3.10-1
Severity: normal
Hi, this is a problem I could not yet pinpoint to the real problem.
I use a notebook in different networks where printers are announced by cups servers.
In one of those networks, cups sefaults shortly after starting.
If I unplug the network cable, cups keeps running, until I plug it in again. So it is something on the local
network which causes cups to segfault.
Other machines with lenny and cupsd running on the same network, don't show that problem.
I did a strace:
sendto(12, "\2\1\0\0\221 \0\0\0\0Y\10\0\2en\0a157.161.4.135,"..., 145, MSG_NOSIGNAL, {sa_family=AF_INET, sin_port=htons(427), sin_addr=inet_addr("239.255.255.253")}, 16) = 145
