           Summary: On a slow network location, Dolphin allows two "new
                    folder" modals then crashes
    Classification: Applications
           Product: dolphin
           Version: 23.08.5
          Platform: Arch Linux
                OS: Linux
            Status: REPORTED

  Target Milestone: ---

Application: dolphin (23.08.5)

Qt Version: 5.15.12
Frameworks Version: 5.115.0
Operating System: Linux 6.7.4-arch1-1 x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 5.27.10 [KCrashBackend]

-- Information about the crash:
Reproduce context: 
While on a network location (smb, gdrive, etc) and experiencing delayed UI
responses due to any sort of network response time issues, sometime when I hit
C+S+N to create a new folder, then the modal window does not immediately pops
up. In such cases, between that delay, if I hit the same key, Dolphin actually
allows me to open two modal window. 

Crashing point: 

Once two modals are open, interacting with the "below" modal window always
crasehs the Dolphin window. 

Expected behavior: 

When I hit the new folder shortcut the first time, Dolphin should immediately
block additional user interactions, even the modal window is not ready due to
various reasons.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
