Error doc files importing (picture "deleted" at witheboard) CentOS 5+

Hello all!

I have some problem with doc, xls and ppt files uploading.
When I am importing an Excel file or Doc to the whiteboard, I get "Deleted"
image.
I have reinstalled openmeetings many times in the different directories, Imagemagic, ffmpeg, sox, pdf2swf and et. also was reinstalled.

If i make conversion manualy via command prompt with jodconverter everything works fine.
Soffice.bin is at port 8100.

I found the following logs:
......

OS CentOS 5+
