I'm not sure if this is a bug in apt, python-apt or software-center. Here's my brain dump
ddebs.ubuntu.com currently has a package with no Description field Package: php5-gearman-dbgsym Priority: extra Section: php Installed-Size: 243 Maintainer: Debian PHP PECL Maintainers <pkg-php-p...@lists.alioth.debian.org> Architecture: amd64 Source: php-gearman Version: 1.1.2-1build1 Depends: php5-gearman (= 1.1.2-1build1) Filename: pool/universe/p/php-gearman/php5-gearman-dbgsym_1.1.2-1build1_amd64.ddeb Size: 50610 MD5sum: 0c9b4932b6a1de927c2f4fb7e388e5d5 SHA1: 60697f6457e71e5197f2a5109d62b7e100616684 SHA256: 8f7f500dd44fa58bb0af6ac573bb22b09b55d536baf28bb20a8aabd373cbdd65 SHA512: 3809e68065c7b8e28c35143411aec449585d443a8a3101839e27671ad1129a33fe69679c9278d6ecea927e6b2b03db216a3812467306fac08826173c81ec3d32 Homepage: http://pecl.php.net/package/gearman I used python-faulthandler to print out a python stack trace when the segfault happens: Current thread 0x00007fdc45a3c740: File "/usr/lib/python2.7/dist-packages/apt/package.py", line 273 in _translated_records File "/usr/lib/python2.7/dist-packages/apt/package.py", line 331 in description File "<stdin>", line 1 in <module> File "/usr/lib/python2.7/pdb.py", line 234 in default File "/usr/lib/python2.7/cmd.py", line 220 in onecmd File "/usr/lib/python2.7/pdb.py", line 279 in onecmd File "/usr/lib/python2.7/cmd.py", line 142 in cmdloop File "/usr/lib/python2.7/pdb.py", line 210 in interaction File "/usr/lib/python2.7/pdb.py", line 158 in user_line File "/usr/lib/python2.7/bdb.py", line 67 in dispatch_line File "/usr/lib/python2.7/bdb.py", line 49 in trace_dispatch File "/usr/share/apt-xapian-index/plugins/display_name.py", line 81 in index File "/usr/lib/python2.7/dist-packages/axi/indexer.py", line 540 in get_document_from_apt File "/usr/lib/python2.7/dist-packages/axi/indexer.py", line 577 in gen_documents_apt File "/usr/lib/python2.7/dist-packages/axi/indexer.py", line 719 in buildIndex File "/usr/lib/python2.7/dist-packages/axi/indexer.py", line 744 in rebuild File "/usr/sbin/update-apt-xapian-index", line 111 in <module> Segmentation fault (core dumped) display_name.py is a plugin from software-center which is doing this: def index(self, document, pkg): … ver = pkg.candidate if ver is None: return if self.val_display_name != -1: name = ver.summary The `ver.summary' line is the one that triggers the segfault by eventually calling into the crashing code in python-apt. python/cache.cc crashes in this line in DescriptionGetFileList() at the call to File(): DescFile = CppPyObject_NEW<pkgCache::PkgFileIterator>(Owner,&PyPackageFile_Type,I.File()); So I'm not sure if the problem is in python-apt here or if there's a bad iterator coming from libapt. ** Also affects: apt (Ubuntu) Importance: Undecided Status: New ** Also affects: python-apt (Ubuntu) Importance: Undecided Status: New ** Summary changed: - update-apt-xapian-index crashed with SIGSEGV in File() + python-apt can SIGSEGV when encountering Packages stanzas with no Description field (was: update-apt-xapian-index crashed with SIGSEGV in File()) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1220013 Title: python-apt can SIGSEGV when encountering Packages stanzas with no Description field (was: update-apt-xapian-index crashed with SIGSEGV in File()) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1220013/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
