Adding label results in assertion

[SuksAE]

When adding a label to line 163 and/or 166 of TypeTray.py

            self.trapezoidSideWall(
                y, h, h+bh, [b, "h", "e", "h"],
                radius=self.radius, callback=[self.yHoles, ], move="up", label="bad")

this results in an assertion:

Exception during rendering: Traceback (most recent call last): File "C:\Daten\Projekte\Python\boxes_SuksAE\scripts\boxesserver", line 517, in serve box.close() File "C:\Daten\Projekte\Python\boxes_SuksAE\scripts..\boxes_init_.py", line 715, in close self.surface.finish(self.inner_corners) File "C:\Daten\Projekte\Python\boxes_SuksAE\scripts..\boxes\drawing.py", line 474, in finish extents = self._adjust_coordinates() File "C:\Daten\Projekte\Python\boxes_SuksAE\scripts..\boxes\drawing.py", line 61, in _adjust_coordinates self.transform(self.scale, m, self.invert_y) File "C:\Daten\Projekte\Python\boxes_SuksAE\scripts..\boxes\drawing.py", line 73, in transform p.transform(f, m, invert_y) File "C:\Daten\Projekte\Python\boxes_SuksAE\scripts..\boxes\drawing.py", line 109, in transform assert(not self.path) AssertionError

Yep, easily reproduced. There is something very wrong in the backend. May take a bit to figure out.

Generally the assert is for parts that have been drawn but have not been finalized by ctx.stroke. The label messing zthis up make the error even more mysterious.

strange behavior in __init__.py:

1st try - function trapezoidSideWall(): changing line 2621 from self.move(overallwidth, overallheight, move, label) to self.move(overallwidth, overallheight, move) --> no assertion, everything works as expected

BUT: 2nd try - function move() changing lines 1184 and 1185 from

            if self.labels and label:
                self.text(label, x/2, y/2, align="middle center", color=Color.ANNOTATIONS, fontsize=4)

to

#            if self.labels and label:
#                self.text(label, x/2, y/2, align="middle center", color=Color.ANNOTATIONS, fontsize=4)

the assertion persists although no label is generated...

Do you have any ideas?

OK, this took a bit longer to look into from the right angle. There's no great mystery here only label not actually landing in the label parameter of the move method... doh
