Description Jung Péter 2018-05-23 11:02:30 UTC

Application: dolphin (17.04.2)

Qt Version: 5.6.2
Frameworks Version: 5.32.0
Operating System: Linux 4.4.126-48-default x86_64
Distribution: "openSUSE Leap 42.3"

-- Information about the crash:
- What I was doing when the application crashed:
I was using SCP protocol inside Dolphin. If I drag and drop a file between 2 tabs, and the drop down list appeares, Dolphin is crashing. If the drop down list doesn't appears (I don't move the mouse pointer iver it), it works fine.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

I can't reproduce here on Dolphin 20.08.1. I opened a fish (scp) connection in a second tab and dropped a folder on it and the popup menu came up ok, was able to copy folder, no crash.

Can you please test on the most up to date version of Dolphin available on your system and confirm if this is still occuring.

I tested it with Dolphin 20.04.2 and it works fine. I think this issue doesn't exist anymore on the recent versions.

Thanks for testing Jung, I'll resolve this bug report and if the issue re-occurs we can open a new report.
