font setPixelsPerUnit crash D:

[lap1994]

From nothing my game started to crash D: it seems there is a error when I call setPixelsPerUnit on my font.

Here is the traceback

And here is the code

self.lightFont = loader.loadFont("assets/cpmonolight.otf")
		self.lightFont.setPageSize(512,512)
		self.lightFont.setPixelsPerUnit(60)
		self.boldFont = loader.loadFont("assets/cpmonobold.otf")
		self.boldFont.setPageSize(512,512)
		self.boldFont.setPixelsPerUnit(60)

I’m using 1.7

From DynamicTextFont:

bool setPixelsPerUnit(float pixels_per_unit)

Set the resolution of the texture map, and hence the clarity of the resulting font.

This sets the number of pixels in the texture map that are used for each onscreen unit. Setting this number larger results in an easier to read font, but at the cost of more texture memory. This should only be called before any characters have been requested out of the font, or immediately after calling clear().

This assertion is raised if you attempt to change this property for an existing font without first calling clear().
