Bug 838364

Created attachment 596919 [details]
File: backtrace

Look like some lowlevel python blowing up, can you reproduce the error

Yes.
(using Cinammon interface), click Menu->System Tools ->Yum Extender
The fault occurs consistently.

please try to to run this from a terminal

python -c "import dbus; print dbus.__version__"

to see if this is a general issue or just with yumex

and this one

yum list expat python

to see the version of python and expat installed

It could be releated to older version of expat

Tried updating to libexpat1-2.1.0-1.3.i586.rpm.
Same problem.

try to reinstall expat, It seams like something is totally broken in your python xml support.

[root@localhost Downloads]# ls expat*
expat-2.0.1-11.fc15.i686.rpm  expat-2.1.0-1.fc16.i686.rpm

Still no joy. yumex won't even start now. is there. or can I turn on a log for yumex?

try:

rpm -Uvh --force expat-2.1.0-1.fc16.i686.rpm

Sorry. No joy. another crash.
Do you want me to submit the crash report?

no need for another crash report

what does this show ?

rpm -qa | grep expat

Look like this is cause by a wrong version of the expat system lib is picked up

https://bugzilla.redhat.com/show_bug.cgi?id=821337

what does this show ?

ldd /usr/lib64/python2.7/lib-dynload/pyexpat.so

bernie : rpm -qa | grep expat
expat-2.1.0-1.fc16.i686

Note this is from /usr/lib NOT /usr/lib64

This is the issue

libexpat.so.1 => /usr/local/lib/libexpat.so.1 (0x0024c000)

it should have been

libexpat.so.1 => /lib/libexpat.so.1 ...

look like you have installed something from source there has installed a libexpat.so.1 in /usr/local/lib/

Thanks for the help.
I'll put /usr/local/lib in the loader path.
