If you go to frame 9 in your trace:
#9  0x07d2e7d1 in rviz::loadTexture (resource_path=...)

and print out resource_path, it should have the texture path.

The fact that it's crashing inside FreeImage is troubling.  The latest debs on my 10.04 x64 system work fine -- are you on a 32-bit system?

This happens each time I try adding the Robot Model display. I tried commenting out the textures in the materials.urdf.xacro in the pr2_description package. But it crashes with the same error. Running pr2_gazebo pr2_empty_world.launch results in a similar crash.

[25998.921563] gazebo[19826]: segfault at 0 ip 015183e1 sp bfcca030 error 6 in libfreeimage-3.14.1.so[13b8000+30e000]

I'm not sure what files it is trying to load. I can try to find out. Could there be some library versioning issues?

Thanks,

Was this a one-time thing, or is it reproducible?  Any chance you can figure out which image it's trying to load, and whether or not it's a valid image?

Hi

I'm having a problem displaying the PR2 model in RViz. I was trying out the pr2_build_map_gazebo_demo. When I add a Robot Model in rviz it crashses with the following message

[ WARN] [1288200457.838841961]: wxWidgets Warning [tiff module: TIFFReadDirectory]
[ WARN] [1288200457.839688381]: wxWidgets Warning [TIFF library warning.]
/opt/ros/cturtle/ros/bin/rosrun: line 35: 28068 Segmentation fault      (core dumped) $exepath "$@"

Running dmesg I get
[13705.992256] rviz[28068]: segfault at 0 ip 0575c3e1 sp bf922890 error 6 in libfreeimage-3.14.1.so[55fc000+30e000]

I'm running on Ubuntu 10.04 and using the binary version of cturtle. Has anyone had similar problem?

Thanks,
Hordur
