Description luca 2024-08-06 16:03:20 UTC 
Veracrypt opens encrypted mounted volume in Dolphin. 
Using plasma apps(gwen, okular or dragon) to open files, bouncing icons appear next to the mouse pointer. But then nothing happens.
Non-kde apps(feh, gimp, vlc) works.

Is this the same issue?

It seems that Qt programs are killed by SIGPIPE
=========================================================================================
56137 write(2, "Qt: Session management error: No"..., 91) = -1 EPIPE (Pipe interrotta)

Prevent  "Qt: Session management error: None of the authentication protocols specified are supported" with unset SESSION_MANAGER helps.

I have the same problem. when I try to open the images with gwenview nothing happens, but if I try with gimp it opens. I open videos with VLC and it opens with no problems.

Comment 4 TraceyC 2024-12-12 19:37:23 UTC 
If something potentially crashed, we need a backtrace of it so we can figure out what's going on. Can you please attach a backtrace of the crash using the coredumpctl command-line program, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl?

Thanks!
Comment 5 Bob 2024-12-20 16:36:04 UTC 
I am facing the same issue on:
KDE Plasma Version: 5.27.11
KDE Frameworks version: 5.115.0
Qt Version: 5.15.13
different kernels from 6.8 to 6.12
Graphic Platform: X11

I tried "coredumpctl" but it says "No coredump found.".

More about symptopms:
Dolphin shows preview of images inside VeraCrypt container, I can open them using some other image vieweing apps (Okular) however my default app Gwenview fails to open them. The same problem with text files. One day I had the same issue when tried to open an image from a HDD which is automounting from fstab (it happened just one day but the other days it worked well).

I will monitor this thread so you can give me debugging instructions and will give your more info.

Since there aren't any coredumpctl files, you can use gdb to see if you can get a backtrace of one of the apps that isn't opening the files, like Gwenview. See this for details:

I used gdb to run gwenview to open particular image file and this is what I got:

Thanks for that output. Well, gwenview is not crashing, so now we know that. I'm marking this confirmed since it's affecting multiple people.

this issue is not relative to gwenview specifically. this is not dolphin issue as well.

I have this issue in many apps (gwenview, kate, element matrix client) while trying to open an image or text file through file picker. in the same time other kind of files (videos) open without problems. the issue also persists across all kinds of drives not only veracrypt containers

give me more debugging instructions and I will tell you more
Comment 11 John 2025-02-07 23:38:30 UTC 
I can confirm this problem too, existing even in Plasma 5.27, most noticeable with Gwenview and Kate.
I've seen it only on Veracrypt + NTFS partitions.
Containers mounted in Debian with Zulucrypt.
The containers mounted in the same OS with the same program, of type LUKS2 + BTRFS don't have any problem.
