PkgDev.publish() seems to be broken

[jdlangs]

On both latest Julia and PkgDev:

julia> PkgDev.publish()
ERROR: MethodError: no method matching find_in_path(::SubString{UTF8String}, ::ASCIIString)

[tkelman]

tagged version or master of PkgDev?

[jdlangs]

master

[wildart]

Do you have recent julia master? What does PkgDev.dir("PkgDev") report?

[jdlangs]

Yes, this was on today's nightly build. PkgDev.dir("PkgDev") gives what I assume is the expected output: "/home/jdlangs/.julia/v0.5/PkgDev"

The same error shows up for the tagged version of PkgDev too so presumably it's from some recent julia change.

[tkelman]

could use a bisect on julia then, I suppose?

[jdlangs]

Sure, I can probably do that in a few hours.

[wildart]

My nightly build works fine.

Did the bisect and found the breaking commit: JuliaLang/julia@ad37021

[tkelman]

nevermind, SubString
