[okular] [Bug 398334] New: Okular crashes while highlighting PDF file

[T. Zack Crawford]

https://bugs.kde.org/show_bug.cgi?id=398334

Bug ID: 398334
Summary: Okular crashes while highlighting PDF file
Product: okular
Version: unspecified
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
Assignee: okular-***@kde.org
Reporter: ***@hotmail.com
Target Milestone: ---

--Software Versions

Application: okular (1.5.1)
KDE Frameworks 5.49.0
Qt 5.11.1 (built against 5.11.1)
Operating System: 4.18.5-arch1-1-ARCH (Linux kernel 4.18.5)
Distribution: Arch Linux
Window manager: i3 (if that matters)
PDF Backend 0.6.5

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

An arbitrary highlightable pdf file was opened with okular (have tried opening
from both Okular>File>Open as well as from thunar and launching from zotero)
The F6 button was pressed to open the review tool with the highlighter option
At least two separate sections of text were highlighted with the default yellow
highlighter. Doing this after highlighting only one section does not produce a
crash (at least not consistently).
CTRL+Z was pressed to undo the last highlighted text
Another section of text was then highlighted
Okular immediately crashes

- Custom settings of the application:

I have added a few extra colored highlighters to the review tool, but I can
make the crash occur using the default yellow highlighter only. Seems not
relevant to the bug.

-- Backtrace:

Application: Okular (okular), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".

I reinstalled okular and glibc in debug mode such that I could get the full
backtrace and now the bug is not reproducible...

backtrace and now the bug is not reproducible...

The crash started happening again. Managed to extract a trace using the gnu
debugger per the instructions at

This didn't really add much.

I guess you may need to type backtrace after the crash to get more info.

Also if you can please run okular through valgrind, please do so and attach it?
