Bug ID: 357430
Summary: Okular crashed when activating “fit width”
Product: okular
Version: 0.22.2
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: okular-de...@kde.org
Reporter: von.kde....@martin-ueding.de
Application: okular (0.22.2)
KDE Platform Version: 4.14.14
Qt Version: 4.8.7
Operating System: Linux 4.2.8-300.fc23.x86_64 x86_64
Distribution (Platform): Fedora RPMs
-- Information about the crash:
- What I was doing when the application crashed:
I edit a LaTeX document that is compiled automatically in the background with
`latexmk -pdf -pvc` which uses inotify and runs `pdflatex`. So the document has
been reloaded a lot of times.
To see some part of an equation more clearly I zoomed in on it by holding the
mouse wheel and moving the mouse. Then I took a raster image using the right
mouse button. Holding that button I selected some area and stored that as PNG
image. A while later I wanted to continue editing and right-clicked into the
document. In the context menu I selected “fit width”. Okular instantly crashed
as I selected that menu item.
Unfortunately I do not remember exactly whether it was compiling in the
background. Then perhaps this action is overlaid with the reloading and then
some race condition occured.
So I would assume that the resizing crashed it. I have tried to zoom in into
other documents and selecting “fit width” again without a problem. This problem
has not occured before at all.
My system is Fedora 23 with RPM Fusion. I use plain Awesome WM without any
desktop environment.
The crash does not seem to be reproducible.
