kdeinit 5 crashed when I was about to reboot the system. DrKonqi said that the backtrace information might be useful so it's shown below. Reproducible: Couldn't Reproduce Steps to Reproduce: Haven't found a way to reproduce. Application: kdeinit5 (kdeinit5), signal: Aborted Using host libthread_db library "/usr/lib/libthread_db.so.1".

Because there is no known way to reproduce this error, there is no way to fix this bug. Suggesting it be closed.
Thank you for triaging, Russel. To the reporter: indeed, a bug that is not reproducible is impossible to solve. Also, if you submit backtraces, please make sure to have working debugging symbols. On Arch, this means you will have to recompile the application with debugging enabled. The backtrace you submitted has no debugging symbols and is sadly useless.
