[Pkg-xfce-devel] Bug#361747: xfce-setting-show: assertion failure followed by segfault

[Stephen Gran]

Package: xfce4-mcs-manager
Version: 4.2.3-1
Severity: important

Hello all,

This is what I see:

steve at gashuffer:~$ xfce-setting-show
(xfce-mcs-manager:19068): libxfce4mcs-CRITICAL **: mcs_manager_add_channel_from_file: assertion `filename != NULL && strlen (filename) > 0' failed

The assertion failure follows:

[pid 19577] stat64("/home/steve/.config/xfce4/mcs_settings/desktop.xml", 0xafa838cc) = -1 ENOENT (No such file or directory)
[pid 19577] stat64("/etc/xdg/xfce4/mcs_settings/desktop.xml", 0xafa838cc) = -1 ENOENT (No such file or directory)
[pid 19577] stat64("/etc/xfce4/xfce4/mcs_settings/desktop.xml", 0xafa838cc) = -1 ENOENT (No such file or directory)

The segfault occurs after:

(fd 3 is the xsession socket here)

Hopefully that's helpful.  I have experimentally moved .config (seems
like a namespace clash waiting to happen, but oh well) and .xfce4 out of
the way, but no improvement.

Take care,
