Reproduce:
Remove the Filter flag

Couldn't reproduce on f43ee4a on linux.

[akien-mga]

I can reproduce it on d592ee6 on Linux. The trick is that one needs to be in Edit mode for the texture in the Inspector for it to trigger a crash.

@AlexHolly As mentioned several times, some more text in your issues who go a long way to save us time trying to understand what they're about and how to reproduce them reliably...

Anyway, gdb backtrace:

[reduz]

those flags should not even be exposed honestly as they are useless in StreamTexture.
