I have several crash like this one when transfering several files, I'm using the compiled binary for linux.
Connecting to Galaxy Nexus and Nexus 10, crash seems random

[hanwen]

can you compile the latest, and try again? If it crashes again, can you tell me how you copied, and send me the output of an strace of the program?

eg. if you used cp, do

strace cp files /tmp/mountpoint

and send the result.

[hanwen]

also, I want to see the complete stderr log
