Bug#908095: Buster: Kwrite crashes while opening a file
Hello,
just found your report and tried to reproduce the crash.
First I assume you copied this text from the crash reporting window?
This information would be way more readable if you would install
the debug symbols for the executable and all the shared objects in
the crashing stack.
Like described here: https://wiki.debian.org/HowToGetABacktrace
In your case this would be:
kwrite-dbgsym libqt5core5a-dbgsym libqt5gui5-dbgsym
libqt5core5a-dbgsym libqt5widgets5-dbgsym
libkf5widgetsaddons5-dbgsym libkf5configwidgets5-dbgsym
libkf5texteditor5-dbgsym libkf5parts5-dbgsym
Then you could press the reload button in the crash reporting window
and it should give a better readable stack.
(That way more likely to attract some maintainer.)
Found it still interesting and came just to the location below,
with the least 3 bytes of each frame matching up to your stack trace,
except the last frame.
But this still only if I used some unicode test files.
I used https://www.w3.org/2001/06/utf-8-test/UTF-8-demo.html
I think the crash happens in the lambda function appendRun,
in case continuationFrom gets a value different to -1.
Unfortunately my test file does not get me that far to the crash.
Therefore I think your file contains a really special case of some
direction changes. Therefore you probably can provide that file or
a copy stripped down to the least causing kwrite to crash?
Kind regards,
Bernhard
