Bug ID: 387408
Summary: Kgpg crashing on getting properties of empty (NULL)
keys
Product: kgpg
Version: unspecified
Platform: Compiled Sources
OS: OS X
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@opensource.sf-tec.de
Reporter: rjvber...@gmail.com
Target Milestone: ---
Application: kgpg (17.08.3)
(Compiled from sources)
Qt Version: 5.8.0
Frameworks Version: 5.38.0
Operating System: Darwin 13.4.0 x86_64
Distribution (Platform): MacPorts Packages
-- Information about the crash:
- What I was doing when the application crashed:
I tried to inspect the properties of a few strange keys I saw in the manager
window (see the screenshot I'll attach)
It turns out that those correspond to entries with a NULL KGpgKeyNode instance;
KgpgKeyInfo() and none of the methods it calls are prepared to receive a NULL
node.
The crash can be reproduced every time.
