IDE 1.6.4 often crashes

Hi there,

i have updated my ide to 1.6.4 and i run into a serious problem.

Very often the ide crashes with 'JavaThread ""'.

This happens when i am idle or during work. Sometimes this happens right after the start of the ide.
Sometimes this happens 5 times within 30 minutes (see my attachments).

I use Windows XP64 (the same as W2k3 Server SP2) as OS.

Please have a look into the crashreports, hope this will help to find the problem.

I have tested with the Nightly-Build (22 May 2015 17:44:43) and the problem is gone.
No crashes within the last 2 hours.
