This is due to a hard coded buffer size, see the end of this message:

This happens when it's part of the way through processing the Status
file. I checked both status and available and the "gnome-guile"
entry has a "Package: gnome-guile" line in both files.
I downloaded the cvs snapshot and checked out alpha_1, and it crashes
at the same spot (p_name="libgdk-imlib1", p->name=0, package in p is
gnome-guile).
Just checked the entry for gnome-guile package. Noticed one
pecularity: the "Depends" line is 330 characters long.
I increased LINE_BUFSZ to 512 in tags.c, and the problem goes away.
A correct solution would be to fix tagfile_read_tags(). If there is
no "\n" terminating the string, then there is more to read. (Unless
EOF.)
