-- Information about the crash:
Hi there,

This is my first ever bug report on KDE. 

I had opened Dolphin file browser, and hit space (habit from Microsoft Windows to select the first time), and it crashed. I have now replicated this a few times. 

This is a nearly stock Fedora Workstation 40 install that I had just completed a few hours ago. KDE Plasma 6. No custom tweaks. Have barely had a chance to play with standard settings, and haven't modified anything related to the Dolphin file browser. 

I'd be happy to answer any more questions you may have. 

Hope this helps!

Thank you.

The crash can be reproduced sometimes.

Indeed it is a bit unfortunate that setups like yours are still affected by this crash. The problem is that this crash wasn't introduced by a change in Dolphin, but by a change in the software Dolphin depends on. Qt 6.7 to be exact. So we released a Dolphin version that didn't crash originally and later Qt was updated on distributions that still used the same Dolphin version. We have promptly changed Dolphin so it no longer crashes, but we couldn't update the previously shipped Dolphin version anymore.

This crash will no longer happen once the Dolphin 24.05 version arrives on your system. I'll mark this bug report as a duplicate of the already solved bug report which first reported this crash.
