crash after mount weirdness

[eighthave]

I was troubleshooting some issues where ./stop-debian.sh does not successfully unmount and lives things in a kind of limbo state where /data/debian is mounted, but no other lildebi mount is. In this case, /data/debian and /data/debian/mnt/sdcard were the only two things still mounted. When I manually unmounted them, Lil' Debi showed me the "Install" button as if there was no image file any more. When I clicked on "Install", I got a crash, the stacktrace is at the bottom of this post.

It seems like something make the sdcard mounting process die, because trying to see it in adb shell did:

shell@android:/ # ls -l /storage/sdcard0/                                      
/storage/sdcard0/: Transport endpoint is not connected

Here's the stacktrace:

It looks like the "killall" logic is killing something it should not. I just got this again. @SDkie any ideas?

[SDkie]

@eighthave : can you help me reproduce it on my device?

[eighthave]

I had it happen a couple of times to me, but I couldn't find a way to reproduce it. I'll keep it in mind.

Hmm, I have a hunch here. It seems that if you are logged into the device using adb shell, the storage mapper thingy will also claim the Lil' Debi loopback mount.
