Bug ID: 355172
Summary: Crash if I quit Okular when the properties dialog is
being displayed
Product: okular
Version: 0.23.60
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
Assignee: okular-devel@kde.org
Reporter: santhiar.anir...@gmail.com
Open a document using okular. In my repro, I opened a text file. Open the
properties dialog, as
File --> Properties. Close okular from a shell using dbus with the command
qdbus `qdbus | grep okular` /okular/okular__Shell_1/actions/file_quit trigger
Note: I was originally using a command line script to drive okular when the
crash occurred.
I narrowed down the repro to the scenario above.
Reproducible: Always
Steps to Reproduce:
1. Open a document using okular
2. Click on File --> Properties
3. From the shell, issue qdbus `qdbus | grep okular`
/okular/okular__Shell_1/actions/file_quit trigger
Actual Results:
Okular crashes with a segmentation fault
Expected Results:
Okular should close smoothly
