Can't add StarDict (.dict, .idx) dictinaries in Ubuntu

Hi all,
I have just installed GoldenDict 1.0.1 on my Ubuntu 11.04, and I tried to add some dictionaries in Starict format (which means *.dict and *.idx files), and some dictionaries in MDict format (*.mdx), and none of them work. I told GoldenDict to look in folders where these files are located, and just nothing happens (and I clicked "Rescan" several times). No error message, nothing. I have no idea why it happens.
(A wish to developers: I'd like to have some GUI to add just a dictionary file, so I would expect an error message to show up when I did something wrong.)
Thanks in advance for your help!
PS. I just tried doing the same with GoldenDict started from the console; after clicking "Rescan" it just says "Load done.", nothing more.
