[Pkg-utopia-maintainers] Bug#623676: libdbus-1-3: dbus fails and causes other applications to segfault since the last update on debian sid

[Stefano]

Package: libdbus-1-3
Version: 1.4.6-1
Severity: critical
Tags: sid experimental
Justification: breaks the whole system

after the last update from libdbus-1-3 1.4.6 to 1.4.8-2 (and dbus and dbus-x11,
same versions), kde startup has failed consistently. Reproducibility is 100%.

/var/log/messages contains quite a bit of the following lines:
kernel: [   94.235717] plasma-desktop[3805]: segfault at 0 ip 00007f8351e74ff6
sp 00007fffe944f860 error 4 in libQtCore.so.4.7.2[7f8351ce2000+29c000]
kernel: [  109.306642] krunner[4295]: segfault at 0 ip 00007f14b0e2dff6 sp
00007fff928364f0 error 4 in libQtCore.so.4.7.2[7f14b0c9b000+29c000]

Then looping on the krunner segfault for a while.

Although it looks like a libQtCore problem, the output of "startx
/usr/bin/startkde -- :1 2>&1" points towards dbus:

process 14065: arguments to dbus_message_iter_append_basic() were incorrect,
assertion "*bool_p == 0 || *bool_p == 1" failed in file dbus-message.c line
2541.
This is normally a bug in some application using the D-Bus library.
Application::crashHandler() called with signal 11; recent crashes: 1
KCrash: Application 'kwin' crashing...


Downgrade to libdbus-1.4.6 solved the issue completely. Upgrade to 1.5.0 did
not.

In short, the system is stable only for libdbus-1-3 <= 1.4.6.

Thanks a lot,
Stefano
