Windows .exe Crash report

[Myaskill]

FTB Launcher version (if this isn't the newest update update and try again): Latest
Minecraft Version: 1.4.2
Java version: 7.0.90.5 64bit
Detailed description of the issue / how can the issue be recreated: This crash seems to be happening at random fairly soon after joining a server, but it's not something I'm able to reproduce by doing certain things. As far as I can tell it's forestry throwing a tantrum.
Error logs: http://pastebin.com/hy6iqRZQ

Edit: It seems to happen when I mouse over some items in the creative inventory

Have you tried redownloading the pack?

 

[Myaskill]

I have, that's always my first step when something goes wrong

Try disabling Forestry through the launcher, open a map, then close the map and re-enable it.
