I am running opensuse 13.2 with kde 5, and this problem has persisted through several updates, I believe. When I insert any usb stick into the laptop, a small window emerges suggesting "Open with File Manager", which seems logical. If I click on this option, the system starts to open hundreds of konqueror instances and goes into 100% load.

I have only found one way to stop this once it begins: pull the power plug and do a hard reset.

I have only found one way to avoid this to happen in the first place: totally disable konqueror (by renaming its executable)

None of those solutions are of course satisfactory in any way. Can anyone tell me why this happens and what I can do to resolve this?
