Comment 1 Parag W 2024-12-07 15:55:10 UTC 
Device is initially connected in No data transfer USB mode which I assume means there is no content to search for? I surrounded dolphinsearchbox.cpp:90 onwards with 

 } else if (m_everywhereButton != nullptr && m_fromHereButton != nullptr) {

and then it stops crashing of course and Dolphin give a Loading cancelled message. 

Changing device connection mode to File Transfer or MTP etc. continues working - I am not sure if this is a good fix though - maybe there has to be a notion of Dolphin understanding where to enable m_everywhereButton / m_fromHereButton depending on whether there's content? Not sure.

Thank you for the bug report. Based on the backtrace, this crash seems to be bug 497021. I'm marking this as a duplicate of that one. You can follow the progress of this issue in the other report.
