Version 7c8b71012c1 crashes when selecting Help -> About

Running 7c8b71012c1 in 64 bit Xubuntu 14.04:

/opt/Slic3r-git/slic3r.pl 

(slic3r.pl:6883): Gtk-WARNING **: gtk_widget_size_allocate(): attempt to allocate widget with width -5 and height 20

Error while autoloading 'Wx::wxCLOSE' at /opt/Slic3r-git/lib/Slic3r/GUI/AboutDialog.pm line 69.

The first three warnings happen during startup. Without loading an STL file, the last error happens instantly after selecting Help -> About in the GUI menu.

The build-from-source dance didn't report any obvious errors, although there were some warnings while building slic3r-XS:

I reported this as issue #2881, and the suggested fix was implemented in pull request #3166. So hopefully it'll be included soon. :)
