Bug ID: 412772
Summary: KRDC crashes when it tries to connect to tigervnc
server
Product: krdc
Version: unspecified
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: uwol...@kde.org
Reporter: 1000.onther...@gmail.com
Target Milestone: ---
Application: krdc (19.04.3)
(Compiled from sources)
Qt Version: 5.12.3
Frameworks Version: 5.60.0
Operating System: Linux 4.19.72-gentoo x86_64
Distribution (Platform): Gentoo Packages
-- Information about the crash:
Got this "server 1", a new Arch Linux instalation. I've installed *tigervnc*
server and run it the simplest way:
vncserver :1
Once entered a password, server creates default files into ~/.vnc and starts
listening.
>From "client 1", Gentoo Linux, I start KRDC client and try to connect to
"server 1". It pops-up the usual dialog inviting me to enter network quality,
save to Wallet, etc. When I finish, application crashes.
The same KRDC client works fine connecting with "server 2", a Debian
installation. But its VNC server is *tightvncserver*.
Using Vinagre client in "client 1", it connects to "server 1" without issues.
I can attach the compile log if it's needed.
The crash can be reproduced every time.
-- Backtrace:
Application: KRDC (krdc), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
