On Red Hat Enterprise Linux 6, rsyslog with imgssapi segfaults

Issue

• Recently updated to rsyslog-5.8.10-2
• Using the gssapi plugin (rsyslog-gssapi) with the $InputGSSServerPermitPlainTCP option
• When starting rsyslog, the following error occurs:

rsyslogd: GSS-API error reading token data
rsyslogd: TCP session 0x7f549c001320 will be closed, error ignored

And then rsyslogd is killed with a segmentation fault error.

Note that the TGT is managed independently of rsyslogd.
