            Bug ID: 445883
           Summary: Okular crashes when trying to save a documents on a
                    CIFS-backed mount
           Product: okular
           Version: 21.11.80
          Platform: Archlinux Packages
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: lars at tuxplace.nl
  Target Milestone: ---

SUMMARY
When I edit and try to save a document on a SMB share mounted locally in /mnt/
using the CIFS driver, Okular crashes.

The document does end up being saved, but with `.part` added to its filename.
The document appears intact when removing the `.part` suffix from its filename
and opening it again.

STEPS TO REPRODUCE
1. Open a document from a CIFS-backed mount.
2. Edit it.
3. Try to save it.

OBSERVED RESULT
Okular crashes and the file is saved with `.part` appended to its filename.

EXPECTED RESULT
The file is saved as normal.
