Bug Description
I was trying to reproduce:
This time, the screen went black, I got a text screen with error messages, but before I could read it, X seemed to switch back to/redraw my normal screen.
Exact steps with more detail than in the previous report:
- Insert USB device (SanDisk Sansa Clip+) with 4GB internal with an additional 16GB SHDC card. (this automounts two devices, one for each storage space)
- Copy some music onto SHDC part.
- Click "safely remove" SHDC part through right-click menu of launcher.
