Bug ID: 483631
Summary: Legacy VI-Mode config crashes kate and kwrite
Classification: Applications
Product: kate
Version: 24.02.0
Platform: Neon
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: application
Assignee: kwrite-bugs-n...@kde.org
Reporter: hoheneg...@web.de
Target Milestone: ---
SUMMARY
Kate and kwrite fail to digest certain legacy configuration and crash during
startup.
STEPS TO REPRODUCE
1. Insert specific config in your $HOME/.config/katevirc :
[Kate Vi Input Mode Settings]

Insert Mode Mapping Keys=

Normal Mode Mappings="+gP,"+gP,vb
Normal Mode Mappings Recursion=false,false,false
ViRegisterContents=inconclusive,\t\t\t\t\t<p>\n\t\t\t\t\t\tIn contrast to
previous evaluation\\, the evaluator determined that <b>no</b> additional
packages that be acquired this time. The distribution DVDs are in fact
self-contained. \n\t\t\t\t\t\t<!--are clearly identified in the
<bibref>ECG</bibref> and a URL is given so that the administrator can find the
additional packages on the SUSE FTP site. Sufficient instructions are given so
that the administrator can reasonably be expected to find and download the
correct additional packages. The evaluator found also that sufficient
instructions are given so that the administrator can check the integrity of the
downloaded packages using the instructions given.-->\n\t\t\t\t\t</p>\n,<dl>\n

Visual Mode Mappings="+y,"+x,"+x,"+y

2. Run kate or kwrite
3. Observe the crash
OBSERVED RESULT
The application crashes during startup.
Output of "strace kwrite" is:

--- SIGABRT {si_signo=SIGABRT, si_code=SI_TKILL, si_pid=680280, si_uid=1001}
---
+++ killed by SIGABRT +++
Aborted
I do not get offered a debug option, therefore, no complete debug logs
included.
EXPECTED RESULT
Kwrite and kate handle the apparently invalid config gracefully and startup
normally.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: KDE Neon user edition
KDE Plasma Version: 6.0.2
KDE Frameworks Version: Version 6.0.0
Qt Version: 6.6.2
ADDITIONAL INFORMATION
I upgraded from KDE Neon user edition where the config used to work.
It suffices to remove the line
Visual Mode Mapping Keys=<s-c-a-m-><s->,<c-x>,<c-c>,<c-insert>
from above config.
