Description Frank Steinmetzger 2021-05-23 23:19:18 UTC 
I got wind of the the migration of FOSS projects to libera.chat and so followed suit with my Konversation installation. I wanted to get a glimpse of the available channels, so I pressed F5 for the channel list, refreshed it and saved it to a file for archive purposes, as I do every few months.

But then the GUI did not react to mouse input anymore. There was no CPU load, so it wasn’t a typical infinite loop. Next I tried Ctrl+Q and it worked: I got the “Do you want to quit” dialog. I cancelled it, and now the GUI worked again.

My current Konversation package is part of KDE 21.04.1. This is the first time I encountered this problem. The last time I used this feature, it was working normally, running on KDE 20.12.2.
Comment 1 ulterno 2025-04-04 15:26:59 UTC 
As of version 1.10.24123 (Arch Repos), the workaround (Ctrl+Q and cancel) does not work.
Comment 2 ulterno 2025-04-04 18:02:39 UTC 
Confirmed problem in master branch.

PROBING

In function: void ChannelListPanel::saveList()
- this variable is : ChannelListPanel('address', name="ChannelListWidgetUI")
- this->parentWidget() : QStackedWidget('address', name="qt_tabwidget_stackedwidget")

For QFileDialog::getSaveFileName(   )
- Setting the option (i.e. the last argument of type QFileDialog::Options) to QFileDialog::DontUseNativeDialog, hence invoking the Qt File dialog, is a functioning workaround
- Passing this->parentWidget() as the parent parameter (1st argument) makes the System File dialog work properly with kio 6.12.0-1

Pass a valid QWidget pointer to QFileDialog

The `this` pointer being passed to `QFileDialog` is not usable 
with the File Dialog provided by KIO.

Use the output of `QWidget::window()` function instead, 
to ensure that a usable pointer is given to the File Dialog provider.
