Description of problem:
Some of the environment variables included with a report could compromise a reporter's privacy: HOSTNAME, USER, USERNAME, LANG, DBUS_SESSION_BUS_ADDRESS.

Version-Release number of selected component (if applicable):
abrt-2.0.2-5.fc15.x86_64

How reproducible:
Always.

Steps to Reproduce:
1. Submit a bug report.
  
Actual results:
"environ:" section contains environment variables with personal information.

DBUS_SESSION_BUS_ADDRESS contains a GUID that could possibly be used for tracking:
$ echo $DBUS_SESSION_BUS_ADDRESS
unix:abstract=/tmp/dbus-uHpRQT8IA7,guid=a07523c37d94b5e4b362b0c900000018

Expected results:
The values of some environment variables are removed, for example:
:HOSTNAME=(removed)

Additional info:
Selinux reports already have certain values removed, for example Bug 698631:
Host                          (removed)
Host Name                     (removed)
Platform                      Linux (removed) 2.6.38.2-9.fc15.x86_64 #1 SMP Wed
