Before commit 1b2826 in lgi, the get_rgba() function on cairo SolidPatterns was
specified like this:
get_rgba = { ret = cairo.Status,
{ ti.double, dir = 'out' },
{ ti.double, dir = 'out' },
{ ti.double, dir = 'out' } },
The above commit fixed this (without saying so) and the code became:
get_rgba = { ret = cairo.Status,
{ ti.double, dir = 'out' },
{ ti.double, dir = 'out' },
{ ti.double, dir = 'out' },
{ ti.double, dir = 'out' } },
The prototype for the corresponding cairo function is:
cairo_public cairo_status_t
cairo_pattern_get_rgba (cairo_pattern_t *pattern,
double *red, double *green,
double *blue, double *alpha);
As you see, this functions gets four double* as arguments and it will save its
result via those pointers. Old versions of lgi call this function with too few
arguments and this will cause a segmentation fault when cairo dereferences an
invalid pointer.

If user changes locale with os.setlocale to a "dirty"
locale (which use comma as decimal separator (not dot), e.g.
hu_HU) `tonumber` will produce "0,6" instead of "0.6"
which causes bad comparision.

Currently it takes `require('lgi.version')`, converts it blindly to
number and compares with another value.
I am using lgi v0.6.1 and that is not convertable to number value,
thus tonumber() returns nil and crashes Awesome.
The fix is to take major and minor numbers only ignoring the rest.

The cairo bindings are quite new in lgi and thus we depend on a quite new
version of lgi. Older versions will fail with lots of weird errors, e.g.:
lib/gears/color.lua:61:attempt to call field 'create_rgba' (a nil value)
