I have a video showing the issue right here (names assigned for grabbing your attention): https://drive.google.com/file/d/1JDI7czT58SKPhJ9rjRaczUy84laU8aob/view?usp=sharing No "Krita has stopped working" message, nothing. Krita just vanishes.
Confirming this. Happens on Linux as well. I'll write a proper bug report. Overview: Krita crashes after creating and deleting a session. Steps to Reproduce: 1) Go to File -> Sessions 2) Create a session 3) Delete said session Actual Results: The application crashed. Expected Results: Krita should delete the session normally Build Date & Platform: krita 4.1.0-pre-alpha Xubuntu 17.10 Krita Lime https://launchpad.net/~kritalime/+archive/ubuntu/ppa Additional Information: Any other useful information. https://webmshare.com/z4w5w Recorded video of said crash Terminal output at the moment of the crash: *** Error in `krita': corrupted double-linked list: 0x0000556fc4479a30 *** I have krita compiled with debug symbols now. I hope it's useful this time.
