F3D segfault with a temporal .vtu file

[mwestphal]

Describe the bug
F3D can open most .vtu files, but vtu file suports temporal data. Its a niche feature that is not used a lot.

To Reproduce
Steps to reproduce the behavior:

1. Download and extract times.zip
2. Open the file using f3d --no-config times_series.vtu
3. Press space
4. Crash
