Description Grigory 2018-02-06 13:17:21 UTC 
Application: kate (18.03.70)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-104-generic x86_64
Distribution: Ubuntu 16.04.3 LTS

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

1. Created a session
2. Worked in the Git-project
3. Closed Kate
4. Opened this session again later
5. Try to close inactive splitters and then the program crashed

- Unusual behavior I noticed:

There are too many "splitters" in the left side of the window. How they were so much uncovered is not clear. Before this, the window was not manually divided into sub-windows.

The crash can be reproduced every time.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault

The accumulation of split elements occurs when another session is opened in the current session (Session -> Open session -> <select session from list>)
