Comment 8 for bug 973494

We'll need to ensure that the sandboxes created with --sandbox-dir are per-release:

[2:56pm] pitti: one scenario where this would fail is:
[2:56pm] pitti: - retrace a bug on package foo version 1
[2:56pm] pitti: - retrace the next bug with foo version 2
[2:56pm] pitti: (unpacks v2 over v1)
[2:56pm] pitti: - retrace the next bug with foo version 1
[2:56pm] pitti: -> does not change any file, as both versions are considered unpacked
[2:56pm] pitti: so you'd gdb against v2 when you want v1
[2:56pm] pitti: now, we do not actually support his yet
[2:57pm] pitti: as apport always takes the latest available version of a package
[2:57pm] pitti: but you will at least need to take care to have a per-release sandbox
