I'm not sure I'll call this a bug, and fixing the code may at any rate
be very difficult.  Fixing it in the markup is trivial, however.

PmWiki treats any line that aligns horizontally with the text of a
previous list item as being a continuation of that list item.  This
is very useful for something like:

    # This is the first item
      * This is a bullet list nested in the first item
      * More bullet list
      More text that is still part of the first item
    # This is the second item

Without this "aligned text continues a list item" feature, getting
the "More text ..." to be part of the first item is very difficult.
Also, the above markup is what people naturally expect to work.

So, in the case you've posted, what we have is:

  :definition:definition text

        Preformatted text
        Preformatted text
   continuation of definition
        Preformatted text

I'm not willing to claim that preformatted text should 
automatically halt the definition list.  One might say that
the heading should halt the definition list... but I'm not
even inclined to agree with that.  

The solution to the problem is fairly simple -- use [==] 
to force the end of the definition list:

  :definition:definition text
        Preformatted text
        Preformatted text
   Preformatted text
        Preformatted text

See this demonstrated at http://www.pmwiki.org/wiki/Test/Preform2 .

Or, use [@...@] for the preformatted text.

  :definition:definition text
        Preformatted text
        Preformatted text
   Preformatted text
        Preformatted text

This is all documented at 
and since PmWiki is behaving exactly as documented (and designed)
I'm inclined to leave things pretty much as they are.
