Description Francesco Cusolito 2020-09-25 15:03:16 UTC

Application: dolphin (20.08.1)

Qt Version: 5.15.0
Frameworks Version: 5.74.0
Operating System: Linux 5.4.0-47-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.19

-- Information about the crash:
I had a sftp folder open for sometimes, in an inactive window. When I interacted again with the same window, trying to navigate to a parent folder, on the same server, through the breadcrumb bar, Dolphin crashed.
It happend me 3 times in the last week, but I'm not able to replicate it consistently.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Aborted

Thank you for reporting this issue in KDE software. As it was reported on an older version, can we please ask you to see if you can reproduce the issue with a more recent software version?  
  
If you can confirm this issue still exists in a recent version, please change the version field and the status to "REPORTED" when replying. Thank you!

I can't reproduce using the instructions from my own bug duplicate 434860

I also can't reproduce the problem anymore.

Comment 15 johann.mourlon 2022-12-01 11:35:35 UTC

Sorry, I cannot reproduce it anymore

Comment 16 Nate Graham 2022-12-01 15:41:03 UTC

Great, seems like it's been fixed at some point!
