Bug 495621

Created attachment 175393 [details]
Crashed Processes Viewer report from Spectacle crashing on "Save As" with an iPhone attached

SUMMARY
In Spectacle's "do things with your screenshot" view, when I click Save As, Spectacle crashes silently (no message, the UI and any boxes/effects drawn on the screen and everything just disappears) -- if and only if my iPhone is attached.

Other KDE applications, like Gwenview and Kate, that would presumably use the same Save As dialog, and that show the iPhone in the locations panel on the left, do not crash when using Save As.

STEPS TO REPRODUCE
1. Plug in an iPhone using a USB cable
2. Take a screenshot with Spectacle
3. Click Save As

OBSERVED RESULT
Spectacle crashes silently, losing the screenshot and any edits, with no visible message

EXPECTED RESULT
The standard KDE Save As dialog appears

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora Linux 41
KDE Plasma Version: 6.2.2
KDE Frameworks Version: 6.7.0
Qt Version: 6.7.2

ADDITIONAL INFORMATION
I tried the Run Interactive Debugger option in the Crashed Processes Viewer - this is the end of what I saw before the (gdb) prompt came up, I don't know if I should have tried to proceed further from that prompt but I assumed the SIGSEGV meant it had crashed in the process of trying to debug?
