Package: libyaml-cpp0.6 Version: 0.6.3-4 Followup-For: Bug #959201 This ABI breakage also affects blender (indirecly via opencolorio). Version 0.6.3-4 does fix the symbol lookup error, however blender will incur a crash soon after with a segmentation fault.
Downgrading libyaml-cpp0.6 to 0.6.2-4 fixes the issue, suggesting that the ABI is still broken somewhere.
