Bug ID: 451685
Summary: Missing regional formats lead to crashes in other apps
Product: systemsettings
Version: 5.24.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: simonisfrede...@gmail.com
Target Milestone: ---
SUMMARY
When selecting regional formats in the KDE system settings, the system does not
check if the selected locales are actually installed.
Choosing and applying a missing locale will succeed, but then cause
applications to crash that attempt to use said locales.
STEPS TO REPRODUCE
1. open system settings > regional settings > formats
2. select a locale not present on the system
3. apply
4. log out and back in
5. open an app that uses the changed missing locale
OBSERVED RESULT
Some apps crash.
I observed crashes originating from boost::filesystem::path::codecvt() trying
to construct a std::locale.
terminate called after throwing an instance of 'std::runtime_error'
what(): locale::facet::_S_create_c_locale name not valid
EXPECTED RESULT
The settings panel should at least warn the user in some way.
One could argue that applying such changes shouldn't be possible.
Ideally, the missing locales should be installed by KDE.
SOFTWARE/OS VERSIONS

KDE Plasma Version: 5.24.3
