Bug ID: 358998
Summary: NULL ptr (this) dereference in KDeclarative starting
KRunner
Product: krunner
Version: 5.5.4
Platform: Compiled Sources
OS: OS X
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: m...@vhanda.in
Reporter: rjvber...@gmail.com
Application: krunner (5.5.4)
(Compiled from sources)
Qt Version: 5.5.1
Operating System: Darwin 13.4.0 x86_64
Distribution (Platform): MacPorts Packages
-- Information about the crash:
- What I was doing when the application crashed:
The attached crash is systematic on OS X.
This ticket is FYI and FWIW, serving at least the purpose of testing DrKonqi in
a real-world scenario. Working on the plasma-workspace package in order to get
DrKonqi to build I noticed that KRunner doesn't have any build-time
dependencies on libraries that are not available on OS X (or "outside" of
plasma). It built without issues, but this is the result when starting it
(without arguments).
