- I am running linux 2.632-29-preempt, 64bit.
After some testing it further, it also happens in trying to browse through the already used images for selecting them as texture.

- Indeed bart.
It happens to me too with 2.56 beta / Ubuntu lucid 64.

- fairly sure this isnt caused by long paths, > 240 chars which blender has trouble with, so Im not sure what to do.
Would one of you be able to run this with gdb and get a backtrace?

- I think you have to more explicit. Which button precisely? The menu botton with tooltip "Browse Image to be linked" ?
Does it crash before opening the menu, while using the menu, or after choosing an image?
Second: this will most likely depend on the context you work on, like editmode or selections of faces you have. You need to help us by pin-pointing this case to something you can save in a .blend, which then causes a crash within 1 or 2 steps. Include the images you try to browse too.

- Hi,
I've done some more tests, and apparently it happens on this object.

- Wow, sorry, my post wasn't complete. I've done more tests, and apparently the crashing happens in this file only. It both happens in edit and in object mode. I've attached a screenshot that shows which button I used, this time in the texture properties, but it also happens in the UV-window with the same button. I must say I started on the project in blender 2.49, and continued in the 2.5 series. Perhaps the file got corrupted somehow?
I hope this helps.

- Likely this is an error scaling down an image for a thumbnail, can you check to see if its a specific directory's files which causes this crash?

- I've reproduced the crash with a new file, using the same image as texture by first loading the image as the texture, then clicking on the button I've shown on the image that I've attached. So I guess you're right.

- Can you try narrow down which image is causing this segfault?
you could do this to temporarily moving images out of the dir until the crash doesnt happen, to work out the offending image.
you could also try run blender with strace to see which image is opened before the crash
strace -e trace=open blender

- Campbell Barton, the Blender crashes if one side (width) of a texture > 32768
When you click on list icon, Blender crashes.Dunno if it is the same bug.

- should have tried making a jpeg this big and viewing thumbnail.
confirmed the crash, looking into this.
