            Bug ID: 428770
           Summary: Dolphin crashed when browsing cifs mounts
           Product: dolphin
           Version: 20.08.2
          Platform: Gentoo Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org
          Reporter: kai at kaishome.de
                CC: kfm-devel at kde.org
  Target Milestone: ---

Application: dolphin (20.08.2)

Qt Version: 5.15.1
Frameworks Version: 5.74.0
Operating System: Linux 5.4.73-gentoo x86_64
Windowing system: X11
Distribution: "Gentoo Base System release 2.7"

-- Information about the crash:
- What I was doing when the application crashed:

I have some folders mounted over CIFS from a remote VPN. When browsing folders
(e.g., clicking multiple folders in a short time), Dolphin crashes. This is
probably some timing issue, I've never seen it crashing on local folders.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Content of s_kcrashErrorMessage: (null)
