Package: tin
Version: 1:1.9.5~20090720-1
Severity: normal

I'm seeing (very) infrequent segfaults when feed-saving articles.
Apparently, this occurs when tin gets a SIGPIPE, probably from writing
to the network socket.  (I have a very flaky DSL, so it's quite possible
the connection sometimes get dropped just when tin is about to write.)

When that happens, pclose(pipe_fp) will segfault, since pipe_fp is NULL.
