Bug ID: 471955
Summary: Konsole crashed after replacing the file for the
selected font
Classification: Applications
Product: konsole
Version: 22.12.3
Platform: Kubuntu
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: konsole-de...@kde.org
Reporter: ben.bl...@gmail.com
Target Milestone: ---
Application: konsole (22.12.3)
Qt Version: 5.15.8
Frameworks Version: 5.104.0
Operating System: Linux 6.2.0-24-generic x86_64
Windowing System: X11
Distribution: Ubuntu 23.04
DrKonqi: 5.27.4 [KCrashBackend]
-- Information about the crash:
I had two tabs open; the first was running Python through Bash, but I hadn't
interacted with it in a bit. In the active tab, I had recently used Bash to
copy v0.050 of the JuliaMono TTF files into ~/.fonts/j/, replacing the v0.045
files already there. This was almost certainly a foolish thing to do, as
JuliaMono was the font selected in Konsole's settings for displaying the
terminal.
The crash didn't happen right away; I moved some other files around via Bash,
then switched to another application. Upon switching back to Konsole, I
attempted to run the command "man curl", at which point Konsole decided it
didn't like me any more. After relaunching Konsole, "man curl" runs just fine
(unsurprisingly).
While I have no evidence to support the conjecture, replacing in-use TTF files
seems highly likely to cause problems.
The crash does not seem to be reproducible.
