Preview error with only Markdown

[Jay Allen]

Hey John et al,

First for the good news: INS and DEL work perfectly now in all of my 
tests, both in block-level and inline context.  Thanks John!

Now for the bad news (sort of).    A bug.

SUMMARY: There is a consistently reproducible problem with entry 
previewing using Markdown (1.0b5) and MT 3.0b2.  It DOES NOT happen 
using Markdown 1.0b4 or "Markdown and SmartyPants".

FULL REPORT:  When I preview an entry using MT 3.0b2 and Markdown 
1.0b5, I get the following consistently reproducible error:

 > Loading template 'preview_entry.tmpl' failed: HTML::Template->new() :
 > Unknown or unmatched TMPL construct at
 >/home/j/www.jayallen.org/cgi/mtbeta/tmpl/cms/preview_entry.tmpl : line 
1.
 >at /home/j/www.jayallen.org/cgi/mtbeta/extlib/HTML/Template.pm line 
2076.

When I preview with any other text formatting option selected 
(including "Markdown and SmartyPants"), I get no error.

I would not bother too much with this considering that it's beta vs 
beta, BUT I just verified that this does NOT happen using Markdown 
1.0b4 and the same version of MT.

Furthermore, if I save the entry (without previewing), everything is 
compiled as expected with no errors.

I am going to do some investigative work, but I thought that perhaps 
someone might know the cause of this offhand.  If you need more 
information, please let me know.
