I can confirm this, same error message, even though i don't think it is that randomly, some appeared on cutscenes (especially in milla's mind where i am right now) or when sucking up cobwebs.

Same problem here.  It happens most frequently whenever I'm using the cobweb collector (regardless of whether I'm using it on cobwebs or not), as well as when I'm jumping around a lot if there's a lot of action going on.

Here's some of the most recent output from when I had to kill it:

Crash log

Sorry for not mentioning before. I'm experiencing this also. I'm using the newest version from Humble Indie Bundle V (2012-06-06), running Fedora 17 with Nvidia propietary drivers.

I will send the output for each time.

Previous time I had to kill it manually. This one it killed itself.

I just hope these help...

Psychonauts and gdb output for 4 crashes

Happens for me too, I attached a lot of crashlogs. A sentence or two what I was doing at the time goes with each of them.

(I'm adding this comment to many bugs that this fix might apply to...sorry if you see it multiple times or it doesn't _actually_ fix your issue.)

Here is a new test build, please try it and report back. It's a 2.1 megabyte
download, so you don't have to redownload the whole game again.

This is meant to fix crash bugs mostly. We still have rendering issues, etc to sort out. If this didn't fix your issue, please report it on this bug. If there are still other unrelated issues, please file a new bug or add yourself to the CC list of one of the other bugs. Here's the open bug list if you want to check for others with the same problem:

    https://bugzilla.icculus.org/buglist.cgi?query_format=specific&bug_status=__open__&product=Psychonauts

Steam users: you'll get this through Steam shortly.

Linux users, download this...

  http://treefort.icculus.org/psychonauts/psychonauts-linux-0.3-patch.tar.bz2

...and unpack it. Overwrite Psychonauts and libSDL-1.2.so.0 with it. This works with either of the first two builds from HumbleBundle.com.

Mac users that aren't using Steam, download this...

  http://treefort.icculus.org/psychonauts/psychonauts-mac-0.3-patch.tar.bz2

...double click it, and run the patcher program it produces.

We'll do a more formal build once we get some feedback.
