FrameMaker 12 Publish Crash

Using Framemaker 12.0.1.331 all publish operations crash if the document contains a UserString of 1 or more characters in a table element.  We use UserStrings in this way to hold metadata about tables such as database keys and effective dates.

The Mif looks like this:  [We would normally have an xml fragment here but this is enough to produce a crash]

<Tbl

  <TblID 10>

<UserString `A'>

  <TblTag `Format A'>

  <TblFormat

Incidently a zero length UserString doesn't result in a crash.

Looks like a bug to me.
