whipper is broken with cdrdao 1.2.5 due to a segfault in cdrdao when it tries to dereference an uninitialized pointer. A one line patch fixing the issue is awaiting review upstream: https://github.com/cdrdao/cdrdao/pull/21 In the meantime, shipping this patch should fix whipper.

Reproducible: Always

Steps to Reproduce:
Run `cdrdao read-toc --device /dev/sr0 --fast-toc cdrdao_fast.toc`
Actual Results:  
cdrdao segfaults:
