Update: turns out there was a sister posting to mine two years ago: http://r.789695.n4.nabble.com/Zinb-for-Non-interger-data-td898206.html
It was then suggested to use a zero-inflated distribution from the gamlss package. It turns out that they do have a zero-adjusted (albeit not strictly speaking inflated) logarithmic distribution. Will try it out and see how it goes...
