Bug#401263: apt segfaults when reading package lists
Package: apt
Version: 0.6.46.2
Severity: grave
Justification: renders package unusable
Whenever I do something with apt-get, it segfaults. Specifically, it
seems that it crashes
when reading package lists. For example, 'update' fetches all files and
displays the 'Fetched...'
line and it also displays 'Reading lists: 0%' or something like that and
then the beginning of that
line is overwritten so it reads 'Segmentation faultsts... 0%'.
I have an uptodate testing here. And yesterday I also updated, so there
are not too many packages
that could cause this.
The packages that got updated today are: gpgv, gnupg, apt-listchanges,
libexif12,
wine, libwine-gl, wine-utils, libwine, libxslt1.1, linux-image-2.6-686,
ppp and xsltproc.
I would guess that apt-listchanges is somewhat related. Uninstalling
that did not fix it.
I have tarred the package lists; available on request.
Here's what GDB thinks about it:
