raise Exception(stderrdata) whe trying to convert from odt to pdf

[ceciliasp]

OS: Ubuntu 14.04 lts

I'm running a Tryton 3.4 (tryton.org) instance and trying to generate a report. This task is requires unoconv (which I have installed v.0.6) and libreoffice (also installed and recently updated). Even so, when I try to generate the report (that should be converted from odt to pdf) I get the following error:

"

File "/trytond/report/report.py", line 300, in parse
data = cls.unoconv(data, report.template_extension, output_format)
File "/trytond/report/report.py", line 320, in unoconv
raise Exception(stderrdata)
Exception: None"
I also made myself sure that unoconv is on $PATH. All other libraries and dependencies are installed and up to date (python3-UNO, uno-libs3, etc).

So I'm out of ideas of what could the problem be. Anyone has a hint on what could be the problem?

Thanks!

It does not seem to be a unoconv problem.
The Exception is produced by report.py.
