SUMMARY
The News widget crashes Krita on startup if fetching news is enabled.

It only happens on Windows Qt6. From https://doc.qt.io/qt-6/qtimezone.html:
> Note: When Qt is built with the ICU library, it is used in preference to the Windows system APIs, bypassing all problems with those APIs using different names.

The backtrace shows this:

It appears to be a Qt bug fixed by the change "Avoid infinite recurision in time-zone abbreviation look-up with ICU" https://codereview.qt-project.org/c/qt/qtbase/+/596973/3
Which is in 6.8.3 (35a82236) and 6.9.2 (f38c0fd3).

STEPS TO REPRODUCE
Open Krita with News enabled.

OBSERVED RESULT
Crashes on loading main window.

EXPECTED RESULT
Doesn't crash, shows news.

SOFTWARE/OS VERSIONS
Krita 6.0.0-beta1 (per K-A; the backtrace is from a build around March 2025, but should be the same.)
