--- Comment #3 from David davidsboogs@gmail.com 2011-04-19 00:37:29 CDT --- Created an attachment (id=34192) --> (http://bugs.winehq.org/attachment.cgi?id=34192) Another terminal log.
I'm also seeing this.
Wine 1.3.18-0ubuntu1 Kubuntu 10.10 amd64, KDE 4.5.5 Kernel 2.6.35-28-generic #49-Ubuntu SMP Tue Mar 1 14:39:03 UTC 2011 x86_64 GNU/Linux VGA compatible controller: nVidia Corporation G98M [GeForce G 105M] (rev a1) Driver: nvidia-current 260.19.06-0ubuntu1
Portal 2 also exits at the menu the same way when launched with the -windowed parameter. (but is windowed until then, saving me from fixing the resolution each time)
I have also attached a log. Note that the point at which it actually (at least visibly) crashes is around the Convar building_cubemaps has conflicting FCVAR_CHEAT flags line near the end, but not sure exactly what the timing is on that.
