Created attachment 984 This is a backtrace and printer the 'info' pointer which is NULL I suspect this may be a library issue, perhaps differences between versions.
Can you check on which file it crashes? I.e. add a debug message to thunar_icon_factory_load_file_icon() and print the file name/path.

To explain a bit further... I added the printf of the filename and parent directory at line 958 of thunar-icon-factory.c. It is not always the same file that crashes Thunar. But info seems to be a valid pointer in thunar_icon_factory_load_file_icon() but becomes null after it is passed to thunar_vfs_thumb_factory_lookup_thumbnail(). Cam
I am not certain this is the exact same problem, but the symptoms are pretty much the same. For Thunar 0.9.* (under xfce4.4) and Thunar 1.0.* (under xfce 4.6), the thunar file manager crashes when scrolling or otherwise viewing a thumbnail. My test reveal that it seem to randomly crash on thumbnail generation for PNG files only. (JPEG files do not cause this problem) The crash happens somewhere near the end of the generation as the thumbnail does finish getting generated. Lets I had a folder with 10 PNG files in the folder, thunar might crash lets say for about 5 of them. Of those 5, the first one it reaches, the thumbnail is generated and thunar crashes. When I open the folder again, the PNG file that caused the crash the first time around no longer crashes and properly shows the thumbnail, leaving only 4 remaining PNG files that will crash thunar. This process can be repeated until all 5 have been generated and then the crashing will never happen again for those 5 files. Copying one of those PNG files anywhere will generate a new thumbnail and will therefore crash again.
