Tab names are missing

[dmemarko]

Cosmetic, but annoying thing.

Does it related to fonts that are missing in Mavericks? If so, how can we know what font exactly to install (and how)?

The bug should only be present (in earlier versions as well) if Xcode is spawned from shell. So you need to find what exactly breaks font rendering in Xcode, or to use a different library injection method (i.e. not DYLD_INSERT envvar)
