Nope, but you may have ended up triggering a bug of some sort.  Is there 
anything in the .log file for the workspace
that indicates a silent error has passed through?

You can also try manually specifying the formatting for your user 
event.  This can be done via the properties of a
single log file (Right click > Properties > System Profiler ...) or on a 
more global level for all log files (Window >
Preferences > System Profiler ...)

The format of the file you are supposed to select here is not documented 
(it is in the documentation food chain
somewhere, but not yet in the released documentation) so for the time 
being I've included a sample configuration
file that is heavily documented and should be able to get you going.

 <!--
  Events definitions are broken down by the event class.
  The user event class is '6' (from <trace.h>), all event codes
  in this section are part of this event class.

 <eventclass id="6" name="User Events">

  <!--
    The user event we want to describe is coded as event #12 within
    the user event class (6).  It is composed of a single 4 byte
    (32 bit) unsigned integer that is followed by a null terminated
    string.  In C the structure might look something like:

     struct event_twelve {
      uint32_t myvalue;
      char     mystring[28];    /* Null Terminated */
     };

    And be emitted using code:

     stuct event_twelve event;
     ... /* Fill event */
     TraceEvent(_NTO_TRACE_INSERTCUSEREVENT, 12, &event, sizeof(event));

  -->   
  <event id="12" sformat="%4u1x myvalue %1s0 mystring" />

  <!--
    In general an event is described as a serial series of event
    payload definitions:

      %<size><signed><count><format> <label>

    Where:
      <size>  
        Is the size in bytes (1,2,4,8)
      <signed>
        Is the signed/unsigned attribute of the value (s,u)
      <count>
        Is the number of items to read (ie an array).  There is a
        special case where if the <size> is 1 and there is _NO_
        format then the <count> can be 0 to accomodate NULL
        terminated strings.
      <format> (optional)
        Is a hint as to how to format this value: d=decimal,
        x=hexadecimal, o=octal, c=character 
      <label>
        Is a string label that can't contain the % character
