I am setting up some patterns to parse Cisco syslog messages.  I noticed that pdbtool will not complete if I have a "%F" anywhere in the string.

Example log message:

%FWSM-1-109006: Authentication failed for user 'test' from 131.212.1.1/43250 to 10.1.1.1/22 on interface management

This does not complete:

pdbtool match -p cisco.xml -M "%FWSM-1-109006: Authentication failed for user 'test' from 131.212.1.1/43250 to 10.1.1.1/22 on interface management"

Nor does simply %F:

pdbtool match -p cisco.xml -M "%F"

It is fine without the %:

pdbtool match -p cisco.xml -M "FWSM-1-109006: Authentication failed for user 'test' from 131.212.1.1/43250 to 10.1.1.1/22 on interface management"

It also seems to have issues with "%S", although not quite in the same way.   Any ideas what could be causing this?
