mydumper crashes with backup from sandbox

[Daniël van Eeden]

MyDumper 0.5.1-3ubuntu1 crashes if I try to use it with MySQL 5.5.30 and 5.6.10 which are running in a MySQL Sandbox.

mydumper -P 5530 -h 127.0.0.1 -u root -p msandbox
mydumper -P 5610 -h 127.0.0.1 -u root -p msandbox

$ gdb --args mydumper -P 5610 -h 127.0.0.1 -u root -p msandbox -v 3
