Changing the Qt widget theme under Plasma's System Settings (Workspace Theme > Look and Feel) or LXQt's Configuration Center (Appearence > Widget Style) while having Konversation running with at least one active channel makes it segfault. Reproducible: Always Steps to Reproduce: 1. Open Konversation 2. Join a channel 3. Open System Settings > Workspace Theme > Look And Feel 4. Change the Qt plugin (if you have only one, then install Breeze or Oxygen) and click Apply Actual Results: Konversation crashes. Expected Results: Konversation should obey the change and apply the theme to its widgets automatically, as it happens to other Qt applications. This is the segfault: Program received signal SIGSEGV, Segmentation fault. 0x00007ffff1f28ced in QWidget::style() const () from /usr/lib/libQt5Widgets.so.5 (gdb) bt #0 0x00007ffff1f28ced in QWidget::style() const () from /usr/lib/libQt5Widgets.so.5 #1 0x00007ffff1efff91 in QApplication::setStyle(QStyle*) () from /usr/lib/libQt5Widgets.so.5 #2 0x00007ffff1f00f06 in QApplication::setStyle(QString const&) () from /usr/lib/libQt5Widgets.so.5 #3 0x00007fffe1154433 in ??
