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)
56137 --- SIGPIPE {si_signo=SIGPIPE, si_code=SI_USER, si_pid=56137, si_uid=1000} ---
56140 <... futex resumed>)              = ? 
56139 <... futex resumed>)              = ?
56138 <... poll resumed> <unfinished ...>) = ?
56140 +++ killed by SIGPIPE +++

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.
