--- Comment #17 from imatii...@gmail.com --- (In reply to Walther Pelser from comment #16) > The search criteria of this bug are: > - Segmentation-fault > - Regression (not with qt <= 5.13) > - Javascript (thermalMonitor with js-files crashes (Plasma too), > kargos without js-files (as far as I modified it with a plugin > as > thermal-monitor ) does not crash. > So I found QTBUG-84363 and it seemed to match.

If this is true, qt 5.15.1 will solve this issue. > > https://bugreports.qt.io/browse/QTBUG-84363 Applied the patch to fix that issue (https://codereview.qt-project.org/c/qt/qtdeclarative/+/300911) to qtdeclarative 5.14.2 on Gentoo. Rebuilt reverse dependencies with "emerge -a --oneshot `equery depends qtdeclarative|awk '{print " ="$1}'`". 49 packages total. Reboot. Still crashes. Just in case went overkill rebuilding dev-qt/*, kde-frameworks/* and kde-plasma/* in that order. Reboot. Still crashes. Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
