Application: kdevelop (5.6.2) Qt Version: 5.15.2 Frameworks Version: 5.80.0 Operating System: Linux 5.11.11-1-default x86_64 Windowing System: X11 Drkonqi Version: 5.21.3 Distribution: "openSUSE Tumbleweed" -- Information about the crash: - What I was doing when the application crashed: Working in a python module with several classes and methods, in a previuos session I folded/closed several classes, kept working on the last class and exited kdevelop cleanly. When I started it again, the folding markers are displaced and the classes are folded in strange ways. Trying to open one of them created the crash. The reporter is unsure if this crash is reproducible. -- Backtrace: Application: KDevelop (kdevelop), signal: Segmentation fault Content of s_kcrashErrorMessage: [Current thread is 1 (LWP 8973)]

This doesn't look related to kdev-python or kdevelop, I'm moving it to KTextEditor.
I would like to fix this, but without a proper way to reproduce this, I can't see how I can :(
Created attachment 145233 [details] Folding gone crazy
I've seen how to reproduce it. Create a trivial python program, for example: class Test: # line added def __init__(self): a = ''' Some text ''' def test(self): # line added # line added for i in range(10): print('hello world') with open('test.py') as f: lines = f.read() fold it in the for loop save the session and close kate modify the file with another editor and insert one blank line where there was already one: class Test: # line added def __init__(self): a = ''' Some text ''' def test(self): # line added # line added for i in range(10): print('hello world') with open('test.py') as f: lines = f.read() Open kate and the folding is gone crazy (like in the attached screenshot). But can not easily reproduce the crash.
The the folding does strange stuff after the file was externally modified on restore of the session is clear, it will just restore the ranges in some best effort way, that will not work. But it should not crash and one should be able to unfold the stuff, that works, doesn't it?
> But it should not crash and one should be able to unfold the stuff, that works, doesn't it? Unfortunately is not what I can see with the little file (and bigger ones).. When I try to unfold the for loop, it folds the method definition and if I unfold the method, the for loop is still folded. Folding and unfolding other parts doesn't help also. I can only see the for loop in the preview of the folded method.
This has been fixed now in the way that Foldings are not restored if the document isn't exactly the same.
