Bug ID: 388228
Summary: Okular crashes when annotating a piece of text
Product: okular
Version: 1.1.3
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
Assignee: okular-de...@kde.org
Reporter: de...@the-user.org
Target Milestone: ---
Hi, I’m using Kubuntu 17.10 with Okular 1.1.3. When highlighting a piece of
text (markup annotation) okular crashes from time to time. It is not easily
reproducible (when I try to highlight the same word again after the crash, it
usually works), but it occurs quite often (after some dozens of annotations
okular crashes again). I have the problem since upgrading from Kubuntu 17.04 to
17.10. The crash occurs when releasing the mouse button after having marked a
segment of the text.
This is the backtrace which I get from gdb:
Thread 1 "okular" received signal SIGSEGV, Segmentation fault.
