Got the following error after logging in after updating to the latest dynamic cam patch:

Error: Fishing (302), condition, runtime

[string "return UnitChannelInfo("player") == GetSpel..."]:1: attempt to call global 'GetSpellInfo' (a nil value)

I checked and the condition script is the following:
return UnitChannelInfo("player") == GetSpellInfo(7620)

Thanks for reporting. Should be fixed with release 2.8.2.
