Description:
Hi,

Our files a mounted via fstab (CIFS) on Ubuntu 16.04 LTS (kernel 4.15) and when we try to open a document (calc, writer, ...), libreoffice is totally blocked (before splash screen) for some seconds (~20-30 sec) and after that it open fine.

It seems that this problem is not present with kernel 4.4.x and if i use vers=2.0 of CIFS it works with all kernels.

It appears more often when the document is saved with a password.

Don't know where is the problem (kernel or Libo) but if someone can test it. 
I do not have debug logs.. If someone can tell me how i can get some debug info, just tell me..

Thanks!



Steps to Reproduce:
1. Mount a network folder over CIFS vers=3.0 in fstab. Use kernel 4.15
2. Open a libreoffice document (try with and without a password in document)
3. Try with a older kernel (4.4 by example) or also another Libreoffice version, 5.4, 5.3

Actual Results:
LibreOffice block for ~20-30 seconds before open

Expected Results:
Have to open quickly without blocking


Reproducible: Always


User Profile Reset: No



Additional Info:
Not sure from which version of LibreOffice it begin. I enter 6.0.5 but i know is from older version.  

It happens on all our computers.

If you have enough disk space and patience, you could try bisecting the problem with our binary repos: https://wiki.documentfoundation.org/QA/Bibisect

You need git installed.

If you are certain the problem is not yet in 5.4, you would download this repository:

git clone git://gerrit.libreoffice.org/bibisect-linux-64-6.0

Then to start things off you would do in the repo directory

git checkout oldest
instdir/program/soffice /path/to/remote/document

Then confirm the problem is present in the latest:

git checkout master
instdir/program/soffice /path/to/remote/document

If problem is not in oldest, but is in master, then start the process with

git bisect start master oldest

...and follow the wiki instructions.

Could you please try to reproduce it with the latest version of LibreOffice
from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the bug is still present in the latest version.
