STEPS TO REPRODUCE
1. Use non en_US locale
2. Start debugging
3. Try expand a variable section which is name has been localized
OBSERVED RESULT
Instant crash.
EXPECTED RESULT
Expanding the variable sections works, regardless of the locale used.
SOFTWARE/OS VERSIONS
KDevelop: 6.4.251200 (25.12.0)
KDE Frameworks: 6.21.0
Qt: 6.10.1, 6.10.1
Arch Linux (Xcb)
Build ABI: x86_64-little_endian-lp64
ADDITIONAL INFORMATION
There is a ongoing, partly related MR
https://invent.kde.org/kdevelop/kdevelop/-/merge_requests/848/commits that
provides some work to help resolve this bug also in kdev-python.
A workaround in meanwhile is to run kdevelop using en_US locale.
