Comment 2 for bug 438001

ok, i found what happens. I have my folder watching pointing to
nonexistent directory, and this is the cause, when i correct this
option to an existing directory all works fine.

The output when folder watching is pointing to nonexistent directory is:

QInotifyFileSystemWatcherEngine::addPaths: inotify_add_watch failed:
No such file or directory
QFileSystemWatcher: failed to add paths: /mnt/data/torrents-linux
Warning: Local domain socket was not closed cleanly, deleting file...

*** NOTE qbittorrent opens ok now , but when u change connection options: ***
