Summary: [model foobar.obj] crashes when no gemwin is created before.

Initial Comment:

when using [model foo.obj] and no gemwin has been created before, pd exits with segfault. 

this also happens on message [open foo.obj(

everything's fine when I create a gemwin, even if i destroy it and then load a patch containing [model foo.obj]

I'm using pd 0.40.3-extended from otherside.servebeer.com intrepid repository.


below output of pd:

i created a thread for this some time ago in the mailing list: 

apparently the cause of these errors seems to be radeon graphics driver or
graphics hardware.

the work around:
before loading any models is still necessary on this computer with current
versions of extended autobuilds. on another computer (nvidia graphics)
everything's fine.

tested today 2009_04_15 on Pd version 0.41-4extended-20090323

I couldn't reproduce this on Mac OS X 10.5/Intel Pd version
0.41.4-extended-20090413.  I am guessing it might have something to do with
that "otherside" build, which is not from the standard build servers.  Try
one of the nightly intrepid builds:

This can not be reproduce on Gem cvs / intrepid.
