Phenomenon: 
 soffice.bin freezes until a NFS access is timed out. 

Reproduction:
 1. File > Open.
 2. Fill the File name field with /net/10.0.0.70/ , an IP address of NFS server.
    Please substitute the IP address with that of your NFS server. 
 3. Press the Open button.

Results: 
 On Solaris, there is a problem that soffice.bin freezes until an attempt of 
 accessing to /net/1 is finished with an error ENOENT because of timeout. 
 It seems that a user has to wait for 500 seconds to see a list of the files 
 in the NFS server if he/she types an IP address of NFS server instead of its 
 hostname. 

 On Linux, there seems no problem from user's point of view. However, some 
 unnecessary accesses can be observed, such as accessing to /net/1, /net/10, 
 /net/10., /net/10.0, and so on.

Expectation: 
 It could be better if soffice.bin would never freeze even though a user fills 
 the File name field with any type of path name in the file selection dialog. 

Solutions: 
Some solutions could be considered. For instance: 
 (a) Removing a series of unnecessary attempts of accessing to partial path. 
 (b) Accepting a ESC key stroke or some similar key one to interrupt the access.
