just discovered a problem with my blender.
when i hit "Use Nodes" there is an immediate crash, no direct backtrace possible.
i stepped through the code with ddd the crash happens when calling glGetFloatv() in ui_rasterpos_safe()
here i collected some useful information about the crash:

this message appears on console after the crash:
X Error of failed request: BadLength (poly request too large or internal Xlib length error)
Major opcode of failed request: 155 (GLX)
Minor opcode of failed request: 1 (X_GLXRender)
Serial number of failed request: 4090
Current serial number in output stream: 4091

Program exited with code 01.

here is a backtrace before the crash:

i can't reproduce the crash in windows but in linux it works in every release which has the node system included so since 2.42, also tried with current svn build.

[WinXP MCE, openSuse 10.2 32bit, AMD X2 5000+. 2GB RAM, ATI Radeon x1650]

my graphic card might be the problem :) i hate ATI never ever again, if so sry for reporting

ill go to bed now, tomorrow or better today ill order a nvidea *joking* and the peach project DVD *not joking*
