Error when using knitrBootstrap version 0.9.0

[lcolladotor]

example('renderReport', 'regionReport', ask=FALSE)

fails when using knitrBootstrap version 0.9.0. That's because knitrBootstrap::knit_bootstrap() returns NULL instead of the character vector with the name of the resulting HTML file. This problem is easily solvable, but first I need to make sure the bioc-git-svn bridge is working properly now that the repo lives in leekgroup. I also have to push the fix to the release branch.

Thanks to Peter Andrews for the bug report.

Also, this bug is not getting picked up by the Bioc build system because the browseURL() call is only made when interactive() == TRUE.
