GLSlideshow Consistantly Freezes

Binary package hint: gnome-screensaver

This happening in both Feisty and the Gutsy Release Candidate. GLSlideshow will start normally, move through a few pictures, and then just freeze. I have used the debugging information found in the man pages and have made a few notes of what I noticed:

1.) Using the "-wireframe" option, the behavior is the same. A few test frames go by and then a freeze.
2.) Using the "-wireframe -fps" option, the behavior is the same.
3.) Using the "-fps -wireframe -debug" option, the behavior is the same.
4.) Using the "-fps -debug" option, the behavior is the same.

For the most part, it freezes with most combinations of those options. This is with version 2.20.0 of gnome-screensaver. Here is my glslideshow.desktop config file:

Comment=Loads a random sequence of images and smoothly scans and zooms around in each, fading from pan to pan. To tell it where to find the images to display, go to the "Advanced" tab on the Screensaver Preferences window. Select "Choose Random Images", and enter your image directory in the text field right below that. (Note: not the the "Advanced" button at the bottom of this window: the tab at the top of the *other* window.) This program requires a good video card capable of supporting large textures.

While writing this bug report, I tried just about every different option I could think of as well as different values for each (i.e. -cutoff 0 -delay 0 -zoom 98) and it's still the same behavior every time. If you need any more information, please let me know. I'm not sure what to include in this report. I'm using a Sony Vaio VGN-FE550G with the Intel 945GM chipset and integrated graphics. Kernel version: 2.6.22-14-generic. GLSlideshow is grabbing the pictures using the specified directory (~/Pictures/2007/) within the .xscreensaver file that I created.

Thanks for any help.

Here's a thread over at the ubuntu forums with two others, besides myself, that are having the same problem:
