If there is a bug in the development version of igraph (which is not really part of R but rather a contributed package) then the correct place to send a message would have been, not to rhelp, but rather to the maintainer. It would of course be necessary to say what the bug appears to be. I don't see any error message or description of a bug in this message. The package DESCRIPTION files says:

BugReports: https://github.com/igraph/igraph/issues

The github page says the proper installation sequence for the development version is:

devtools::install_github("gaborcsardi/pkgconfig")
devtools::install_github("igraph/rigraph")

Rhelp is not the correct place for pre-release bug discussion of contributed packages.

Again, the github pages suggests that you send issues to the correct mailing list: igraph-help mailing list
