UNO IllegalArgument during import phase: Source file cannot be read. Unsupported URL

[squeezer44]

I'm using Libreoffice 4.2: Export in all different filetypes is working properly.
After that I cloned the current version of unoconv from GitHub (git clone https://github.com/dagwieers/unoconv) and installed it with sudo make install.

As I tried it out with unoconv -f pdf test.odt everytime the same error occured:
UNO IllegalArgument during import phase:
Source file cannot be read. Unsupported URL

After deeper research I can't find the reason and hope you can help me.

Thanx a lot!

Strange behaviour, but I solved the problem.
I removed the not used dependencies with
sudo apt-get autoremove
Thus removed the libreoffice-core.
As I started unoconv it works properly.
I guess there has been some dependencies inbetween my running Libreoffice 4.2 Instance and the libreoffice-core. However - not it works.
