github ate some code :) take a look at screenshot — http://dl.dropbox.com/u/3829178/discuss/unoconv-error.png

Hi,

It's not simple to understand what the errors mean. Even for me :-) We get the error from OpenOffice or LibreOffice. Since unoconv 0.4 we added the specific error-code as part of the output (code: 1287) which me help the OpenOffice/LibreOffice developers to track the error to something specific.

Googling this error code may give some relevant information:

http://groups.google.com/group/jodconverter/browse_thread/thread/5e081b76625d59ca?pli=1

If you find the cause and we can fix it in unoconv, let me know.

Problem solved. These files are the problem. I don't know where they came from:

.~lock.index.pdf#
.~lock.index.html#

[dagwieers]

Mike, that's in fact interesting. Maybe unoconv should remove them if encountered, or at least report when they exist they could cause problems.

Thanks for the feedback. I'd like to keep this open until we have more info about this.

I added this possibility to the README's troubleshooting section. Since this is likely caused by LibreOffice/OpenOffice crashing, it's better to fix the cause than trying to workaround it. It's no clear whether we can make sure stale lock files are in fact stale...
