How to reproduce:
1. Create or open any project
2. Install Vector Graphics package
3. Drag and drop user's attached 'Gelbelsee-West.svg' file into the Project window

Expected results: The SVG image is successfully reimported
Actual results: Editor freezes

Reproducible with: 2018.4.14f1 (1.0.0-preview.32), 2019.2.16f1, 2019.3.0f2, 2020.1.0a15 (preview.10 - 2.0.0)
Reproduced on Windows and Linux and with all package versions down to preview.6 - 2.0.0 (could not test below due to package errors)
Could not test with 2017.4 due to Package Manager not being introduced yet

Notes:
- Reimporting the image by selecting 'Assets -> Reimport' causes the same freeze
- After opening the project again, a message appears in the Console window that says:
"A default asset was created for 'Assets/case_1202456-Gelbelsee-West.svg' because the asset importer crashed on it last time.
You can select the asset and use the 'Assets -> Reimport' menu command to try importing it again, or you can replace the asset and it will auto import again."
- The last Editor.log entry shows this:
"Start importing Assets/case_1202456-Gelbelsee-West.svg using Guid(5b4af88f3630895c0818ffed913d9332) Importer(-1,)"
- You can find the original image attached by the user
