GUI freeze then crash when launching a rocket with inventory overlaid

[zamolxis]

Launched a rocket and while the animation was playing, I pressed E to bring up the inventory/crafting menu.
The graphics froze (while the sounds and music were still going on). A bit later, the loading screen popped up, stuck at 0% (loading mods).
Clicking something brought up the "Error" screen.

Thanks for the report, you ran out of memory. I suspect for the same reason as 117300.
