Exact steps for others to reproduce the error

Open new file with default layout.

Go to File -> Import -> Scalable Vector Graphics (.svg) and select the provided file.

Found the issue. The .svg contains path commands like : a44.457 44.457 0 00-1.265 2.29. The a command needs a multiple of 7 parameters. Our number parser parses this as ['a', '44.457', '44.457', '0', '00', '-1.265', '2.29']. Notice the '00'. This becomes worse when the second to last number is not negative: a2.571 2.571 0 00.637-.698 -> ['a', '2.571', '2.571', '0', '00.637', '-.698'].
