Does it happen when you start the applet or only when you interact with it in a certain way?

No need to paste the traceback twice. Please paste the output of this command:
/usr/bin/nvidia-settings -q GPUCoreTemp

[Alessandro Ghione (alex81)]

62.
    'GPUCoreTemp' is an integer attribute.
    'GPUCoreTemp' is a read-only attribute.
    'GPUCoreTemp' can use the following target types: X Screen, GPU.

Formatting seems to be different in your output than the applet expects. To make sure, please run this in terminal:
python
# now you'r in the python console, it starts with >>>
import os
os.popen("/usr/bin/nvidia-settings -q GPUCoreTemp").read()
# here you get some output, paste it in the bug report
quit()

Thanks for your help. The problem is kind of fixed in rev. 1520. The applet won't crash anymore. It crashed because it couldn't interpret the output of nvidia-settings but the output you gave in comment #10 is o.k. so I don't know what's the ultimate cause of this crash. (However the output in comment #7 might be problematic because the value 62 seems to be on a new line.)
