RHBA-2010:0850 - Bug Fix Advisory

Topic

An updated python-gudev package that fixes a bug is now available.

Description

Python-gudev is one of the core components for Red Hat Network (RHN)
registration process.

This updated python-gudev package fixes the following bug:

• Under some circumstances, using the 'rhn_register' command to register a

system with the Red Hat Network (RHN) might fail. When this issue is
encountered, the 'rhn_register' command will return an error similar to:

# rhn_register
Segmentation fault (core dumped)

or

# rhn_register

• **MEMORY-ERROR***: rhn_register[11525]: GSlice: assertion failed:

sinfo->n_allocated > 0
Aborted (core dumped)

With this update, the aforementioned errors are no longer returned and using the
'rhn_register' command works as expected. (BZ#637084)

All users of python-gudev are advised to upgrade to this updated package, which
resolves this issue.
