Wrong Dub used

[russel]

Opening a project with a dub.sdl appears to work, the "find Dub" dialogue I used "auto find" which it did and everything seemed fine. However on editing a D file in the project, the following error occurs:

Unable to parse dub configuration: Cannot run program "/usr/bin/dub" (in directory "/home/users/russel/Repositories/Git/Masters/ApproxGC_D"): error=2, No such file or directory

So it seems that the found Dub is ignored in the plugin configuration.
