I have a longtable environment which I split for PDF output with a  
few \newpage's. In HTML the vertical space between the last row "on  
the last page" and the first row "on the next page" is not constant  
and shrinks in two cases to zero.

There is one error with an included PNG image in the end:

	Execute script `File.lg'

	sh: -c: line 2: syntax error: unexpected end of file

When I try to view the "PostScript document text conforming at level  
2.0 - type EPS" file (from an earlier run, last year) in gv I get  
this error:

	Error: /syntaxerror in --%ztokenexec_continue--

Gv shows a blank rectangular area which correlates to the PNG image's  
size. I can't find in any file the invocation of ImageMagick's  
convert that obviously produces the faulty EPS file.


BTW, Eitan: how can I persuade htlatex to create a united HTML and  
CSS file?


At home I found by chance \ifHtml: does this fail because it's latex  
that creates the DVI file? Is it only useful when one's back- 
converting HTML?
