Filemanager: More than 10 subfolders it borken the path. Any solution?

If i have more than 10 subfolders in filemanager (the fist folder is in the path /) then filemanager or webdav broken and says HTTP FORBIDDEN error. How to put more than 10 subfolders? If you create a new subfolder in the 10th subfolder filemanger says
"Unavailable path" and if you try to put a file filemanager says the same message.

I see that error_log in apache appear this:


sqlfs_stream_wrapper::stream_open(sqlfs://default/ ...../uny.pdf,w,5) execute() failed: Array


PHP Warning:  fopen(sqlfs://default/..../juny.pdf) [function.fopen]: failed to open stream: "sqlfs_stream_wrapper::stream_open" call failed in /var/www/vhost/xxx.com/home/html/egw/phpgwapi/inc/class.vfs_stream_wrapper.inc.php on line 183

It's a bug? i say that i use filemanager with a lot of files and folders, but i need to create more than 10 subfolders please.
