[libreoffice-users] help track an issue

If anyone can help me understand how to track/trace this issue, I would 
appreciate it.

Software
OS: Mageia4 64 bit
KDE4
LibreOffice 4.3.7.2 (Build ID 4.3.7.2.1.mga4)

Physical
HP Pavilion p6-2419
Kingston USB memory stick, (DT 101 G2 ... 16GB)

Filesystem
Ext4 in both cases

Procedure
    (1) Insert USB drive
    (2) Access USB drive with Dolphin
    (3) Close Dolphin
    (4) Open LibreOffice
        (4.1) Close empty text document
        (4.2) Open existing spreadsheet on local drive
            (4.2.1) Compete task(s) in spreadsheet
            (4.2.2) Save changes to local drive under same name/same 
location
            (4.2.3) Save As to USB drive with similar name ... date 
added to name
        (4.3) Close spreadsheet
    (5) Exit LibreOffice

Problem
Sometimes (seems to be random) at step 4.2.3 the Save As fails ... error 
message indicates that the original document is opened by another user?  
Sorry, I cannot find the actual error message at the moment ... will be 
able to supply it when it happens again, of course.

Note
I follow the above procedure carefully because it seems to experience 
this particular issue the least.  The only exception would be if steps 1 
through 3 have already been done, and the USB drive is still attached 
(has not been removed).

Question
What can I do to track/trace this issue on my machine?

Thank you
Regards
Fred James
