Package: bzr-gtk Version: 0.103.0+bzr792-3 Severity: critical Dear Maintainer,
Having bzr-gtk and python-gtk2 installed at the same time causes "pydoc -k foobarbaz" to crash, because 1) pydoc has to import all packages in order to find out what modules they contain 2) your package bzrlib.plugins.gtk.branchview causes gi.repository.Gtk to be imported 3) python-gtk2's package gtk imports _gtk 4) importing both of those modules causes a SIGSEGV Anyone hoping to take a look at the crash itself might (or might not) find this script helpful:
import sys import resource #import pkgutil # A big stack wastes time/space in GDB. # (This size was chosen for i386; adjust as needed.) resource.setrlimit(resource.RLIMIT_STACK, (32*1024, -1)) # import bzrlib.plugins.gtk.branchview from gi.repository import Gtk import _gtk #for importer, modname, ispkg in pkgutil.walk_packages(): # print modname, ispkg, importer # sys.stdout.flush()
This is marked critical ONLY because having your package installed causes "pydoc -k" to fail, not because I think you're actually to blame for this: the ultimate problem is 4) above, which is of course a problem with python-gi and python-gtk2; bzr-gtk just exposes this booby-trap to "pydoc -k". I would report a bug for that, too, but I don't know which package to report it against :-(. P.S. This would have been easier to debug if the python in wheezy had debug syms available <http://bugs.debian.org/681348>. Thanks to Jakub Wilk for building me a python with the patch I posted on <http://paste.debian.net/220873/>: maybe all I got out of valgrind was the fact that it was a stack overflow, but having debug symbols was *vital*. -- System Information: Debian Release: 7.0 APT prefers testing APT policy: (990, 'testing'), (500, 'unstable'), (1, 'experimental') Architecture: i386 (i686) Kernel: Linux 3.2.0-4-686-pae (SMP w/1 CPU core) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages bzr-gtk depends on: ii bzr 2.6.0~bzr6526-1 ii gir1.2-gconf-2.0 3.2.5-1+build1 ii gir1.2-gtk-3.0 3.4.2-4 ii gir1.2-gtksource-3.0 3.4.2-1 ii libcanberra-gtk3-module 0.28-6 ii python 2.7.3~rc2-1 ii python-gi 3.2.2-1 ii python2.6 2.6.8-0.2 ii python2.7 2.7.3~rc2-2.1+valgrind Versions of packages bzr-gtk recommends: ii bzr-dbus 0.1~bzr52-2 ii gir1.2-freedesktop 1.32.1-1 ii gir1.2-notify-0.7 0.7.5-1 ii python-gi-cairo 3.2.2-1 pn seahorse <none> Versions of packages bzr-gtk suggests: ii bzr-loom 2.2.0-2 pn bzr-search <none> -- Hi!
