Description Jaime Torres 2020-02-28 17:14:50 UTC 
Application: dolphin (19.12.2)

Qt Version: 5.14.1
Frameworks Version: 5.67.0
Operating System: Linux 5.5.4-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

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

I was adding metainformation to several folders (rating) and then renaming then one by one. After one rename, the folder became the last in the view, so I used keyboard to go to the top of the view to rename the next one, after 5 times, speeding time after time, dolphin crashed.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
29	  return SYSCALL_CANCEL (poll, fds, nfds, timeout);

Comment 1 Elvis Angelaccio 2020-06-07 22:45:19 UTC 
Can you reproduce this crash? If yes, please provide a valgrind log.
Comment 2 Jaime Torres 2020-06-20 08:29:36 UTC 
As soon as I can use valgrind again I'll try to reproduce it.
Lately valgrind always crashes dolphin (and other kde programs) before showing any window.

Application: Dolphin (memcheck-amd64-linux), signal: Segmentation fault

Comment 3 Jaime Torres 2021-12-19 10:15:01 UTC 
FYI: I'm still unable to start dolphin under valgrind.
At least I know where the problem is: The included PCRE versión in Qt5, which uses previous versions of https://github.com/zherczeg/sljit
which causes, with development version of valgrind, the errors:  
==32395== Conditional jump or move depends on uninitialised value(s)
==32395==    at 0xF034DED: ??? (in /memfd:sljit (deleted))
==32395==    by 0xDF671F9: ???
before crashing.
Any other Qt program that doesn't uses PCRE just runs as it used to.
