[Raspberry Pi] Errors during miniDLNA plug instalation

Hello,
First of all thanks a lot for that sophisticated media server, respect!
There is problem when trying to install (using web interface) the miniDLNA plug. There is a lot of errors, fetching files is a problem as the installer writes).
I was reading other thrads, nothing found - probably this is only on Raspberry Pi platform problem.

Thanks in advance for your response!
