Pictureflow and crypt_firmware will probably also throw a panic at you...
One of the many reasons why this target is still listed as unstable.
If you have a build environment set up, you can circumvent the panic by increasing the main stack size IIRC (seems to work for me anyway), but this is not a fix for this issue...just a work-around.
PS: Was it just "*PANIC*" or was it "*PANIC* 'some other text' "?
