SUMMARY STEPS TO REPRODUCE 1. 2. 3. OBSERVED RESULT Immediate crash [joshua@joshua-spectre ~]$ konsole /usr/include/c++/11/bits/random.tcc:3055: void std::piecewise_linear_distribution<_RealType>::param_type::_M_initialize() [with _RealType = double]: Assertion '__sum > 0' failed. KCrash: Application 'konsole' crashing... EXPECTED RESULT Running Konsole SOFTWARE/OS VERSIONS Linux/KDE Plasma: fedora 34 x11 (available in About System) KDE Plasma Version: KDE Frameworks Version: 8.82.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION The problem went away when I removed .local/share/konsole, and returns when I put a profile colorscheme back into the directory from before the upgrade. The colorscheme includes a random rotating background color. When I reenable the feature "Edit Current Profile" -> "Appearance" -> "Color Scheme & Font" -> "Edit" -> "Randomly adjust colors for each session", it again crashes, even if it was running successfully before. Also Filed a bug with fedora. Don't know if its their bug
