I cannot reproduce this with either the latest stable or current development versions of Blender.

Just tested, neither mentioned 33bdd91fb8, nor 9b7754883b get the assert. I was opening new file (cmd + N )

This still happens for me.
Did you test with debug or relwithdebinfo? I should specify this.

That's strange. I am not sure what to check if the freeing sequence is correct exactly. I was looking into this for a bit and haven't found anything strange.

Perhaps @Harley would know more?

I can certainly take a look. But wondering if you've asked me just because I've generally poked around in there or was it because of some specific thing that I could have broken? Just in case that narrows things down.

I'll commit a fix for this. It's a rather subtle problem caused by 8b10e1b457 and b7f86ff722.

I just thought, that you are file browser guru, so you would be good person to ask :)

@iss - I just thought, that you are file browser guru, so you would be good person to ask :)

Well thanks! Although I thought it more likely you were trying to remind me of some dumb thing I forgot that I had done in there.

I did look at that error and thought I was on the right track with that previews task, but then I saw Brecht's fix and I was nowhere near. LOL
