 It's a Gentoo bug. Gentoo's `/usr/bin/python` is a symlink to `python-
 wrapper` which invokes the version of python selected by
 `/etc/env.d/python/config`, `$EPYTHON`, etc.

 Unfortunately, it also inspects `argv[0]` (which it has no business
 doing), which breaks when `argv[0]` is something other than the Python
 interpreter or the script.

 g.gui passed "wxgui" as `argv[0]`; I "fixed" this in 7.0 with r39764, but
 that was before I discovered that it was Gentoo's bug. I'm not sure
 whether this should be back-ported or reverted.

 This bug has been reported at
 [http://bugs.gentoo.org/show_bug.cgi?id=286191], but the Gentoo developers
 only appear to be concerned with how it affects Gentoo itself.

 As to what to do about it: part of me says to revert it on principle
 (Gentoo isn't Microsoft, and shouldn't assume that the rest of the world
 will change to accommodate them). OTOH, I don't see any advantage to
 passing an "unusual" value for `argv[0]`.
