Hi, I just upgraded from Fedora 29 to Fedora 30 and am using KDE. After upgrade, the Korganizer cannot open again and every time crashes before the windows appears. The error message is: Executable: korganizer PID: 9137 Signal: Segmentation fault (11) Time: 6/23/19 12:51:47 and the generated crash information is Application: KOrganizer (korganizer), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

What Qt version are you using? Even though the debug symbols are missing, your backtrace looks pretty much like bug#404275. That was a bug in Qt (the crash only occurs with certain time zones), and should be fixed in Qt 5.12.3.

Thanks. It does seem exactly the same. I tried to change the timezone from Asia/Tokyo to Asia/Shanghai or America/New_York. But it does not work. Do you know how to update to Qt 5.12.3 without default repository? I'm using Fedora 30.
