Description Casey 2020-09-17 21:56:48 UTC
Application: dolphin (20.08.1)

Qt Version: 5.15.1
Frameworks Version: 5.73.0
Operating System: Linux 5.8.7-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

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

Accessing specific media folder on USB external hard drive. The drive has two partitions, one HFS legacy and one newly created EXT4. The specific folder on the EXT4 partition contains 45GB of music files, copied via rsync from an internal drive -- a backup. 

- Unusual behavior I noticed:

When opening the folder, it displayes duplicated contents -- album folders -- but does not close. When I manually close Dolphin it triggers the crash report. 

Dolphin has been crashing spradically doing various operations on similar data -- sizable media libraries -- typically on NFS connected shares but also on a local drive... it appears when files are being added, in progress, via torrenting. 

But this is the first event that is reproducable every time. 

This issue also occurs running "super-user" Dolphin. 

PLease advise if I must install debug resources. Thanks.

The crash can be reproduced every time.

I'll comment here since I also encountered an issue with Dolphin crashing relating to duplicate filenames.

But my case is a little different as is the coredump.
I was copying files from one folder to a subfolder using Dolphin. I noticed filenames that appeared to be same. I looked closely and saw no differences. I also used the console's autocomplete to see there was truly only one file (no duplicate).

I think I may have tried opening the file or maybe editing the name to see if it was a glitch, or maybe going "back" a folder (don't remember), and Dolphin just disappeared, eventually writing out the coredump:

Ugh, I also meant to mention that I initially did a search for "dolphin" here, which showed this report.

Then I tried to search for "dolphin duplicate" (without quotes. looking for other reports) and this report was not listed even though "dolphin" and "duplicate" are in the report title.

I don't know if there's reporting for the site's search feature, but this sure seems like a horrible implementation if it can't bring up this report from my very simple search:

With a search using this two keywords I get 176 tickets, one of them being yours, so the search works fine. The search index isn't updated every minute.

Are you using the Tree view mode in Dolphin?
Comment 4 vindicator 2020-09-20 03:11:02 UTC
Yeah, I saw this post now listed (compare with the partial (top) list I included in my previous post).

I don't know if the search function simply doesn't examine the subject/title of the report, or doesn't consider variations of a word (duplicates, duplicated, ...). But I especially expected the search to come up with this report solely based on the words being in the title.

Yes, most of the time (including this), I do have it set to tree-view. And this is also the only time I've ever experienced it (in case you are wondering if I can replicate it using a different mode).
