invalid memory address or nil pointer dereference when trying to delete with --version-id AND --dry-run

[haraldkubota]

Expected behavior

Not throwing a nil pointer dereference error

Actual behavior

Throwing a nil pointer dereference error:

mc rm --version-id 2890fbb8-c435-4336-bcef --dry-run "os2/downloads/Fun with spaces.txt"
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x28 pc=0xf8c519]

Steps to reproduce the behavior

mc rm --version-id v2 --dry-run os2/downloads/TheRegister.pdf

If the version-id is valid (exists), then no nil pointer deref error is thrown, with or without --dry-run.
If the version-id looks valid (e.g. take any version-id and modify a digit), then no nil pointer deref error either.
If the version-id is totally wrong (e.g. "v2") or missing the last section (e.g. missing the "-e77fd4616826" in "2890fbb8-c435-4336-bcef-e77fd4616826"), then an error is thrown when the --dry-run option is used. Without "--dry-run" it simply outputs nothing (but it also does nothing since the version-id does not exist). No nil pointer deref error.

mc --version
