Comment 1 christophe.prudent 2025-02-02 11:33:26 UTC

same behavior w/ pgAdmin4 (8.14) to open an SQL file

Comment 2 Waqar Ahmed 2025-02-02 11:49:01 UTC

1. Use a newer Kate version. The one you are using is not supported anymore
2. We can't anything about the crash. Seems like there is an allocation failure and the program is crashed. Perhaps you ran out of memory

thanks to your response
I folllow LTS version Kubuntu, without installing more recent version of each application

else, I want to precise that error seems to be general about KDialog: using Kate, or pgAdmin4 version 8.14, or Okular ...

best regards

Comment 4 christophe.prudent 2025-02-02 20:06:22 UTC

same issue as 499410

Comment 5 Waqar Ahmed 2025-02-03 06:40:58 UTC

You can get a newer version here: https://kate-editor.org/get-it/

I doubt it would help. This is not a bug anywhere. Qt just fails to allocate memory for whatever reason and then the program crashes. Maybe your system is broken Or something else, you need to figure it out yourself. But the important thing is, that "we can't do anything about your bug".

This is why I closed it earlier. I will leave it open now as I am tired wasting my time already.

ok thanks to your jobs, -:)
I wanted just say that my problem doesn't restrict to Kate, but more generally for each application to open/save a file with KDialog
Kate, pgAdmin4, Okular, ...

I will try to understand what happens...
Have a good day
