Item2392: GenPDFWebkitPlugin doesn't work on Windows

I'm having problems generating a correct PDF (Foswiki on windows)

- wkhtml2pdf-0.8.3.exe works perfectly (I'm able to convert a existing html-file) - opening a wikipage with "...?contenttype=application/pdf" generates an empty PDF

digging further into "lib/Foswiki/Plugins/GenPDFWebkitPlugin.pm" shows, that the tempfile with the html-output is already empty.

I added

open blabla "C:\\TEMP\\bla.html";
print blabla "$_[0]";

bla.html then contains correct output. So it seems the problem is in File::Temp. I have no idea how to debug this.

Apaches log shows

What's interesting: the files actally are written. I inserted the following after execution of wkhtml2pdf:

use File::Copy;
copy($htmlFile, "C:\\Temp\\bla.html") or die "File cannot be copied.";
copy($pdfFile, "C:\\Temp\\bla.pdf") or die "File cannot be copied.";

and bla.html indeed contains the correct content, though bla.pdf is a empty pdf file

Wait - that's only true if I open a separate filedescriptor instead of using File::Temp for creation of bla.html (and printing the html to this filedescriptor).

open blabla "C:\\Temp\\bla.html";
print blabla "$_[0]";
