[galaxy-dev] Problem in Manage data Library

We have found that, in Galaxy, when we add dataset to a library under Manage data libraries, Galaxy sometimes detects the type of the file and sometimes does not. What I have noticed is that it detects the type of the file when we select "Copy file into Galaxy" under "Copy data into Galaxy?" option and does not detect it when we select "Link to files ..." Is this a known issue? Regards, Sachit
