I am running the latest version of blender to date (2.54 beta sep 11)

When I load blender with the default file, and change the main 3D view to the UV/image editor, and press Image > Open, it hangs for a few seconds and crashes with the following report:

Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_INVALID_ADDRESS at 0x000000001c3533f8
Crashed Thread: 4

The full crash report is attached.

On my friend's laptop (alluminium macbook) this crash is sparodic, but can be repeated by changing the path URL to desktop, then pressing cancel.

This only happens wiht this version on my computer, not with 2.4

Restarting etc does not effect the bug

Thanks
