Well, did I just have an exercise in frustration. I needed to get a couple pictures off my phone (using MTP) so I plugged it into my computer. It asked for permission on my phone, I allowed it - then KDE reports the MTP process died.
So I tried a second time but faster tapping 'allow' on my phone and got it to list directory contents. I selected the five pictures I needed, and dragged and dropped them to their destination (Pictures folder). The phone then asked for permission five time in about 500ms - not enough to allow them. So the MTP process crapped out again. I repeated this three times and cursed at KDE (it used to work, I haven't had to copy files off my phone in more than six months) and emailed them to myself. Does anyone know why KDE/mtp would exhibit this type of behaviour? Dan
